Multivariate Modeling of Elite Performance Across Video Game Genres

This report presents a rigorous statistical analysis aimed at quantifying an individual’s gaming proficiency across a broad spectrum of genres and titles. Through systematic evaluation of key performance indicators — including kill/death ratios, completion rates, high-difficulty clearances, and competitive rankings — we derive an estimated overall skill percentile. The findings position the subject within the extreme upper tail of the gaming population, exhibiting rare mastery across competitive first-person shooters, high-difficulty character action games, complex RPGs, technical racing simulators, and cognitively demanding puzzle titles.

The analysis indicates that this individual’s composite gaming achievements are statistically exceptional. Their estimated overall gamer skill percentile is 98.93%, placing them within the top ~1% of the global gaming population. More strikingly, the probability of a single individual independently attaining this specific constellation of high-percentile accomplishments is approximately 1.06 × 10 − 47. When scaled to the current world population of approximately 8.062 billion, this yields an expected frequency of just 8.53 × 10 − 38 individuals with this precise performance profile. This vanishingly small figure highlights the profound rarity and exceptional nature of the subject’s cross-domain gaming aptitude.

This unique performance profile suggests the emergence of a “polymath gamer” archetype—an individual whose competencies transcend genre-specific specialization. Whereas most elite players achieve mastery within a narrow range of mechanically similar titles, this subject demonstrates consistent high-level performance across a spectrum of dissimilar genres, including first-person shooters, character-action games, bullet-hell shmups, racing simulators, and strategic RPGs.

This breadth implies a core set of transferable cognitive and motor abilities, likely encompassing advanced pattern recognition, rapid decision-making under time constraints, exceptional visuomotor coordination, long-horizon strategic planning, and sustained psychological resilience. Such domain-general proficiencies indicate a higher-order gaming intelligence characterized by adaptability and abstracted skill transfer, rather than rote memorization or mechanical repetition. This broader versatility amplifies the significance of the percentile estimations derived earlier, positioning the subject not merely as a genre expert, but as a rare cognitive outlier within the gaming population.

This individual ranks within the top 1.07% of the global gaming population, indicating exceptional proficiency relative to peers worldwide.

A Statistical Framework for Assessing Comprehensive Video Game Skill

The evaluation of individual proficiency within the expansive domain of video gaming presents considerable complexity, primarily due to the heterogeneous nature of game genres, mechanics, and player strategies. Conventional performance metrics—such as esports competitive rankings or speedrun leaderboards—are inherently game-specific and lack a standardized framework for cross-title comparison. This study aims to address this gap by developing a composite model that integrates diverse achievement indicators—including kill/death ratios in first-person shooters, completion rates in role-playing games, and ranking metrics in puzzle titles—into a unified, quantifiable measure of overall gaming skill percentile.

This analysis seeks to provide a rigorous, data-driven response to the inherently complex and multifaceted question of quantifying overall gaming proficiency. The methodology entails calculating individual percentile ranks for discrete games using empirical performance data alongside well-founded assumptions. These individual metrics are then integrated via a robust aggregation framework to produce a composite skill percentile. A key aspect of this quantification involves estimating the extremely low joint probability of a single individual independently attaining this specific constellation of elite accomplishments across multiple gaming domains. Throughout the report, full transparency is maintained regarding all assumptions, mathematical formulations, and data limitations to uphold the analytical integrity and reproducibility of the results. The findings ultimately characterize the extraordinary rarity of the subject’s combined achievements within the global gaming population, thus providing a statistically substantiated validation of their elite status.

Methodological Foundations and Assumptions Underpinning Skill Measurement

Accurate estimation of an individual’s overall “gamer skill percentile” necessitates the establishment of a well-defined methodological framework and explicit articulation of underlying assumptions. In this context, a skill percentile represents the proportion of the player population that an individual outperforms; for instance, the 99th percentile denotes superior performance relative to 99% of the relevant player cohort within a specific game or challenge.

General Assumptions Underlying Percentile Estimation

In instances where precise distribution data for specific game performance metrics—such as kill/death ratios, completion rates, or ranking distributions—are unavailable, it is standard to assume that player skill and achievement follow either a normal or log-normal distribution. This assumption aligns with established statistical conventions for large populations, wherein performance typically clusters around a central tendency, and extreme levels of skill occur with exponentially decreasing frequency. For legacy titles or games lacking current active player data, proxy metrics such as total game ownership (sourced from achievement-tracking databases) or concurrent user counts from platforms like SteamDB are employed to approximate the relevant player base. It is important to acknowledge the inherent limitations of these proxies, as the actual active population may be smaller, temporally variable, or subject to demographic shifts.

For this analysis, only legitimate, cheat-free gameplay is considered — anything achieved using invincibility glitches, save-state abuse, or similar exploits is not counted.

Weighting Factors for Composite Skill Percentile

When aggregating individual game percentiles into a singular overall skill metric, it becomes necessary to apply weighting factors that reflect the relative significance of each achievement. Relevant considerations include the size of the player population—since achieving a high percentile in a larger player base implies greater rarity—the competitive structure of the game, with player-versus-player (PvP) or leaderboard-centric titles typically providing more direct measures of skill, and the intrinsic difficulty level, where games characterized by exceptionally low clear rates denote higher skill thresholds. Although more sophisticated weighting algorithms could be constructed to account for these variables, the primary analysis employs an equal-weighting scheme across all distinct achievements. This methodology offers a balanced representation of the subject’s multifaceted mastery, highlighting the breadth of elite performance across diverse gaming genres. Subsequent sensitivity analyses may evaluate alternative weighting strategies to assess their influence on the composite skill percentile.

Game-by-Game Breakdown: Detailed Analysis of Individual Achievements

This section presents a systematic, data-driven examination of the subject’s key gaming accomplishments. For each title, we outline pertinent performance metrics, specify underlying assumptions, and provide the calculated skill percentile within the respective player population.

HowLongToBeat (2025) Over 310 Games Beaten (Top 0.73% of 606K+ Users)

Example illustration of the statistics available from HLTB.

The subject’s HowLongToBeat profile reports “Over 310 Games Beaten,” situating them within the top 0.73% of more than 606,000 users tracked by the platform. This percentile is directly provided by HowLongToBeat, confirming the subject’s relative standing within its extensive user base.

This metric captures a distinct dimension of gaming proficiency—namely, breadth of experience. While individual game-specific accomplishments demonstrate depth of skill within particular titles, the total number of completed games reflects exceptional dedication, substantial time investment, and a high degree of adaptability across a wide range of game genres and platforms. As a meta-achievement, it signifies an overarching gaming aptitude characterized by rapid learning and flexible engagement with diverse gameplay mechanics. This broad scope of accomplishment robustly complements the subject’s domain-specific skill metrics, reinforcing their characterization as a “polymath gamer” who exhibits both profound mastery and expansive versatility across the gaming ecosystem. The estimated percentile corresponding to this achievement is the 99.27th percentile.

The subject’s extensive completion record spans an exceptionally broad spectrum of video game genres, including but not limited to: fighting, beat ’em up, run-and-gun, platformer, role-playing (RPG), racing, action-adventure, first-person shooter (FPS), puzzle, sports, music/rhythm, strategy, simulation, third-person shooter, party, adventure, rail shooter, katamari-style, sandbox, microgame collections, stealth, and rogue-like/lite titles. This diverse range further underscores the subject’s adaptability and comprehensive gaming expertise across varied mechanical and cognitive demands.

CrossFire: KD 2.0, over 232 recorded ACEs, 128 MVPs during prime.

CF Promotional Wallpaper

The individual’s Kill/Death (K/D) ratio in CrossFire is reported at 2.0. For comparison, in a similar competitive first-person shooter such as Call of Duty: Warzone, a K/D ratio of 2.0 corresponds approximately to the 97th percentile, while the median K/D ratio is near 0.9. Assuming that the distribution of K/D ratios in CrossFire parallels that of Warzone, this places the individual’s performance well within the elite echelon of players.

Beyond traditional statistical measures such as K/D ratio, the distinction between ACEs and MVPs provides additional granularity in evaluating competitive skill. ACEs—awarded to the player with the highest kill count across both teams at the conclusion of a match—serve as a proxy for raw combat lethality and mechanical dominance. Conversely, MVPs recognize comprehensive contributions, including total damage dealt, kill streaks, and critical eliminations that impact match outcomes. These accolades reflect advanced decision-making, strategic situational awareness, and consistent execution under pressure.

The subject’s consistent accumulation of ACEs and MVPs indicates not merely proficiency in fundamental metrics but a capacity for impactful, high-level performance in competitive environments. This qualitative dimension acts as a substantial multiplier on the raw K/D-based percentile estimate, justifying an elevated overall skill percentile. Taking into account both K/D and competitive accolades, the individual’s estimated percentile ranking in CrossFire is approximately the 98.5th percentile.

The individual’s estimated percentile ranking in CrossFire is approximately the 98.5th percentile. It is noted that earlier in their gaming history, their K/D ratios may have ranged between 2.2 and 2.7; however, these figures cannot be independently verified due to account loss. Their most recent peak performance over the past 2–3 years reflects a consistent ~2.0 K/D ratio across multiple competitive modes, including Search and Destroy, Team Deathmatch, Free for All, Weapon Master, and Weapon Master Team Deathmatch.

Old School Runescape PK Account KDs (Account 1, 656 kills 77 deaths 8.5 K/D) (Account 2, 413 kills 42 deaths, 9.8 K/D)

The iconic land of Gielinor.

The subject’s Old School RuneScape (OSRS) Player Killing (PK) accounts demonstrate extraordinary kill/death ratios, with Account 1 recording a ratio of 8.5 (656 kills to 77 deaths) and Account 2 exhibiting a ratio of 9.8 (413 kills to 42 deaths). Within the OSRS PvP community, a K/D ratio exceeding 1 is widely regarded as indicative of a “force of nature,” underscoring the exceptional nature of the subject’s performance. Ratios of 8.5 and 9.8 reside in the extreme upper tail of the distribution of K/D ratios for the game’s competitive PvP environment.

While it is conceivable that elevated K/D ratios could result from selectively engaging less skilled opponents, the maintenance of such ratios across hundreds of kills strongly suggests consistent dominance against a heterogeneous player base. This level of sustained success implies a deep mastery of complex combat mechanics, optimal equipment configurations, player movement tactics, and counter-strategies within the OSRS Wilderness. Such proficiency transcends mere statistical outperformance, reflecting expert-level strategic execution in a highly competitive and dynamic environment.

Given these factors, the subject’s performance is conservatively estimated to correspond to the 99.99th percentile within the OSRS PK community, placing them at the pinnacle of PvP mastery.

Note: For readers less familiar with Old School RuneScape terminology, “NH PKing” refers to “no-honor” player killing—a PvP style characterized by the unrestricted use of all available tactics and items (e.g., protection prayers, Saradomin brews, freezing spells) to maximize survival and opponent elimination. This aggressive and strategic playstyle contrasts with “honor” PKing, which adheres to self-imposed limitations such as refraining from overhead prayers or excessive healing. The subject’s reported K/D ratios derive from two NH PKing accounts—a 1-defense pure build and a 60-attack main—engaged at high-conflict zones such as Lava Dragons, Black Chinchompas, Revenant Caves, and the Wilderness Altar. This mode of play exemplifies a dynamic, high-stakes environment akin to a digital “wild west,” emphasizing adaptability and tactical ingenuity.

Ninja Gaiden II (2008) Xbox 360, Mentor (1.53% Clear Rate) & Master Ninja (1.20% Clear Rate)

Ryu Hayabusa wielding the deadly tonfa.

The clear rates for Ninja Gaiden II on Xbox 360 are notably low, with reported completion percentages of 1.53% on Mentor difficulty and 1.20% on Master Ninja difficulty. These statistics reflect the game’s formidable challenge, particularly the Master Ninja mode, which is often characterized in the gaming community as a “seriously dreadful experience” that may require up to two years for a dedicated player to complete.

An important consideration in this analysis is the adjustment of these clear rates to account for known in-game exploits. Community discourse has documented the existence of the “Invincible Ninja Glitch” on the Xbox 360 version of Ninja Gaiden II. While not conferring full invulnerability, this glitch facilitates easier progression, albeit with restrictions on mobility and efficacy in certain combat scenarios. Additionally, save state exploits—where players save and reload to despawn enemies—have been noted as a method to artificially increase clear rates. Given the exceptional difficulty of these modes, it is plausible that a significant fraction of the small subset of players who have officially cleared the game utilized such exploits.

A conservative qualitative adjustment estimates that approximately 50% of reported clear rates on both Mentor and Master Ninja difficulties are attributable to play involving these or similar exploits. Applying this adjustment yields effective legitimate clear rates of: ● Adjusted Mentor Clear Rate: 1.53% * (1 - 0.50) = 0.765% ● Adjusted Master Ninja Clear Rate: 1.20% * (1 - 0.50) = 0.60%

This integrity correction is essential for accurately assessing the rarity of authentic, skill-based completions. By excluding non-legitimate clears, the individual’s accomplishment is positioned within an even more exclusive subset of players who have surmounted one of the most demanding challenges in video gaming through genuine skill and perseverance. Consequently, the estimated skill percentiles, adjusted for exploit use, are: ● Estimated Percentile (Mentor, Adjusted): 100 - 0.765 = 99.235th percentile. ● Estimated Percentile (Master Ninja, Adjusted): 100 - 0.60 = 99.40th percentile.

Note: The proportion of players utilizing exploits to clear Ninja Gaiden II’s Master Ninja difficulty is estimated more conservatively at 10–25%, based on discussions from TrueAchievements forums, Reddit, GameFAQs, and the cumulative view counts (~99,000) of “Ninja Gaiden 2 invincibility cheat” videos on YouTube. Regardless, the sustained clear rate of approximately 1.20% since the game’s 2008 release remains extraordinary. Comparable clearance rates are predominantly observed only within the shoot ’em up (SHMUP) genre, underscoring the game’s extreme difficulty. While the mention of the Mentor difficulty clear may be redundant given the Master Ninja completion, the remarkably low clear rate at the second-highest difficulty remains noteworthy. The subject has also engaged extensively with Ninja Gaiden 3: Razor’s Edge at Master Ninja difficulty, though has not completed the full campaign, focusing instead on challenges such as Ninja Trials and Chapter Challenge modes. Based on hundreds of hours of gameplay exclusively on Master Ninja difficulty, the subject estimates being within the top 10% of Master Ninja players—effectively the upper decile of the already elite 1% who complete this mode. This self-assessment further supports the applied percentile adjustment and underscores the subject’s high skill tier.

Ninja Gaiden Σ2 (2009) PC, Master Ninja (4.0% Clear Rate)

Ryu Hayabusa and Momiji

The individual achieved a 4.0% clear rate on Master Ninja difficulty in Ninja Gaiden Σ2 for PC (Steam). This difficulty level presents significant challenges consistent with the franchise’s reputation, including mechanics such as instant-kill grabs that limit the utility of healing items and heighten the skill ceiling. No widely documented game-breaking exploits or performance-inflating glitches have been identified for this version, supporting the conclusion that this clear rate accurately reflects the rarity and skill required for completion. Accordingly, the estimated skill percentile associated with this achievement is conservatively maintained at 92.20th percentile.

Note: The Master Ninja difficulty in Ninja Gaiden Σ2 remains a significant test of player skill, characterized by stringent enemy behaviors and punishing mechanics such as instant-kill grabs. Despite the relatively low clear rate, the player has demonstrated mastery of these challenges, though this entry focuses primarily on the percentile estimation rather than detailed completion circumstances.

Hotsuma of Shinobi (2002)

The individual's completion rates for Shinobi on PS2 are remarkably low across multiple difficulties: Normal (1.58%), Hard (0.56%), Super (0.56%), and Stage EX (0.56%). These figures align with detailed achievement data from platforms such as RetroAchievements, which report similarly low percentages for stage and difficulty completions. There is no evidence indicating the presence of game-breaking exploits that would artificially inflate these full-game clear rates. Consequently, these completion percentages are treated as accurate reflections of the game’s inherent difficulty and the rarity of these accomplishments.

● Estimated Percentile (Normal): 100 - 1.58 = 98.42nd percentile. ● Estimated Percentile (Hard): 100 - 0.56 = 99.44th percentile. ● Estimated Percentile (Super): 100 - 0.56 = 99.44th percentile. ● Estimated Percentile (Stage EX): 100 - 0.56 = 99.44th percentile.

Note: The subject reports that overcoming the final boss of Shinobi on PS2 initially required several months of dedicated effort. Over time, sustained engagement with the game’s rich replay value has fostered continuous improvement, culminating in recognition as one of the top players globally. Although speedrunners maintain superior performance benchmarks, the subject’s proficiency markedly exceeds that of the average player in this challenging title.

Shinobi (2002) PS2, Full Game Time - Normal - Hotsuma (49.008167 minutes, 1st place out of 1962)

In addition to completing Shinobi across multiple difficulty levels, the individual recorded a full-game completion time of 49.008 minutes on Normal difficulty playing as Hotsuma, ranking 1st among 1,962 recorded players. While the official world record for a complete-game Shinobi speedrun stands at 38 minutes and 29 seconds, securing the top position within a competitive community of nearly 2,000 players reflects an exceptional level of proficiency.

Speedrunning represents a distinct facet of elite gaming skill, demanding exhaustive knowledge of game mechanics, impeccable execution, and highly optimized route planning.

Note: Although established speedrunners significantly outperform the subject in terms of raw completion times, the subject uniquely secured first place on this specific RetroAchievements leaderboard, demonstrating notable skill and dedication within that particular competitive context.

Nightshade (2003) PS2, Normal (3.65% Clear Rate) & Hard (0.81% Clear Rate)

Hibana

The individual’s clear rates for Nightshade on PS2 are 3.65% for Normal difficulty and a notably challenging 0.81% for Hard difficulty. These percentages correspond with achievement data reported on platforms such as RetroAchievements, which document similarly low completion rates across stages and difficulties for Nightshade. There is no evidence within the reviewed research materials of game-breaking exploits or glitches that would artificially inflate these clear rates. Consequently, these figures are treated as accurate representations of the inherent difficulty and rarity of successful completions in this title.

● Estimated Percentile (Normal): 100 - 3.65 = 96.35th percentile. ● Estimated Percentile (Hard): 100 - 0.81 = 99.19th percentile.

Note: Nightshade is a personally enjoyable title, though its emulation is often unstable. Additionally, issues with the RetroAchievements set—such as glitches and malfunctions—have limited further play beyond the recorded achievements.

Crimzon Clover Promotional Art

The individual achieved a "Novice Boost 1cc Type Z" clear in Crimzon Clover WORLD EXplosion with a reported clear rate of 8.3%. Achieving a "1cc" (one credit clear) in a bullet-hell shoot ’em up (shmup) represents a significant skill milestone, requiring mastery over complex patterns and sustained concentration. Although the "Type Z" mode is noted to render the gameplay "more manageable," this adjustment does not substantially diminish the inherent challenge of completing a 1cc. Furthermore, the unlock conditions for Type Z necessitate a considerable time investment, underscoring the player’s dedication. The reported clear rate of 8.3% for this mode is accepted at face value. Accordingly, the estimated skill percentile for this achievement is 91.70th percentile.

Note: The 1cc clear rate for Novice Boost on World Ignition—a now-delisted version of the game—is lower, at approximately 5.0%. This discrepancy may stem from performance differences or other confounding factors inherent to that release.

While the Type-Z ship offers enhanced power, the individual has also achieved multiple 1cc clears on Novice Original difficulty using both Type-III (a personal favorite) and Type-Z ships, with clear rates of 6.2% and 12.4% respectively across World Ignition and World EXplosion. These consistent accomplishments on Novice Original reinforce the conclusion that the 1cc clear on Novice Boost is not an isolated occurrence but indicative of genuine skill rather than chance.

Mach Storm (2013) Arcade/PC, Super ACE Rank/1cc (Unknown Clear Rate)

Mach Storm (2013) Start Screen

The individual achieved a "Super ACE Rank/1cc" (one credit clear) in Mach Storm. Although a precise clear rate for this accomplishment is unavailable, attaining a "1cc" in an arcade-style combat flight simulator combined with the "Super ACE Rank" denotes a remarkably high level of skill and mastery. The game comprises multiple combat missions with varying difficulty levels, each demanding precise execution.

Excellence in a specialized title like Mach Storm represents a qualitatively different form of elite performance compared to percentile rankings in larger, more mainstream games. While the player base is smaller, the dedication and nuanced skills required to achieve a "Super ACE Rank/1cc" suggest a profound and refined mastery within this niche genre community. The rarity of such an achievement remains exceptionally high, reflecting a sustained commitment to overcoming challenging gameplay in less widely played titles. Accordingly, the estimated skill percentile for this accomplishment is qualitatively assigned at 99.50th percentile.

Note: Remarkably, the individual achieved a 1cc with maximum ranks in Mach Storm on their second attempt. While the game presents intense and demanding gameplay, it remains unclear whether this rapid success is attributable to inherent ease or the player’s innate skill.

Tetris Battle (2010) PC, Immortal Rank 101 (Unknown Rate)

Tetriminos.

The individual attained Immortal Rank 101 in Tetris Battle, a ranking near the apex of the game's tier system. The Immortal Rank (101–105) is positioned just below the highest tiers of Demi-God (106–110) and God of Tetris (110 MAX). Advancement beyond Rank 101 necessitates acquiring 50 Stars per promotion, reflecting a substantial increase in required performance consistency and success against elite opponents. For comparative context, achieving an Immortal rank in other competitive titles, such as Dota 2, corresponds to placement within approximately the top 0.5% of the player base.

Competitive ranking systems are calibrated to stratify players by skill level, with the upper echelons representing the most exclusive and elite cohorts. Achieving Immortal Rank 101 in Tetris Battle directly quantifies the player’s exceptional competitive prowess within the puzzle and Tetris subgenre. Consequently, the estimated skill percentile for this accomplishment is placed at 99.90th percentile.

Note: The individual paused progression beyond Immortal Rank 101 in Tetris Battle due to the substantial grind required—namely, accumulating 50 Stars per rank-up. Notably, the ranking system places Immortal above Grandmaster and Legendary Grandmaster tiers, although the individual personally favors the latter titles. Additionally, their 40-line sprint (40L) time of 1:00.673 places them in approximately the 83rd percentile within the Jstris community. Considering Jstris’s skilled and competitive player base, this likely corresponds to a top 5–10% standing across the global Tetris population, encompassing casual and licensed title players. This indicates broad proficiency across diverse competitive Tetris variants.

Yakuza 0 (2017) PC, Legend Difficulty (2.0% Clear Rate)

Kiyru Kazuma and Goro Majima

The individual completed Yakuza 0 on Legend Difficulty, a setting with a reported clear rate of approximately 2.0%. This difficulty level is characterized as comparable to Kiwami but without exploitable mechanics, with the game’s “Climax Battles” representing some of the most demanding challenges encountered. The lack of documented exploits at this difficulty supports treating the 2.0% clear rate as an accurate indicator of the achievement’s rarity and the requisite player skill. Accordingly, the estimated skill percentile associated with this accomplishment is 98.00th percentile.

Note: This is the first clear rate in the analysis that the individual considers somewhat uncertain. While many players reportedly struggled with a specific shooting section in Yakuza 0 Legend Difficulty, the individual’s 15 years of experience playing CrossFire rendered this segment comparatively manageable. Whether influenced by imposter syndrome or simply a differing perspective, the individual estimates the true clear rate for this difficulty could be substantially higher—potentially 10% or more.

Ys VIII (2016) PC, 100% (6.6% Clear Rate)

Ys VIII Wallpaper

The individual achieved 100% completion in Ys VIII, corresponding to a reported clear rate of 6.6%. Notably, data from PSNProfiles for the PS4 version indicates a higher "100% Completed" rate of approximately 15.8%. This discrepancy may arise from platform-specific player behaviors, as completion rates often differ between PC and console audiences, or from a more rigorous definition of "100% completion" employed by the individual—potentially encompassing all optional challenges, time trials, or hidden objectives beyond the standard trophy criteria. Considering the individual’s established pattern of high-level achievement, the 6.6% clear rate is adopted here as a conservative estimate of their accomplishments rarity. Consequently, the estimated skill percentile for this feat is 93.40th percentile.

Note: Ys marked the individual’s introduction to truly “hardcore” action RPGs. They particularly enjoyed Oath/Origin, describing it as “Zelda on crack—minus the boring puzzles.” (Apologies to Zelda fans—this is an action games blog, after all!)

Mario Kart 64 (1996) N64, 1st Place All 150cc Cups (3.80% Clear Rate)

Mario Kart 64 3D Render

The individual secured first place in all 150cc Grand Prix cups in Mario Kart 64, a comprehensive achievement with an estimated clear rate of 3.80% based on data from RetroAchievements players. This statistic reflects the accomplishment’s recognized difficulty and rarity within the player community.

Securing first place across all 150cc cups represents a significant mastery of the game’s offline challenges. The attainment of 16,000 VR reflects sustained high-level performance in the game’s competitive online multiplayer environment. While 16,000 VR is below the maximum 99,999 VR, community consensus identifies approximately 10,800 VR as a critical threshold marking the “final choke point” in lobby matchmaking and a recognized benchmark of true mastery. Given the similarity between Mario Kart 8 on Wii U and Mario Kart 8 Deluxe on Switch, this combined offline and online accomplishment underscores an exceptional degree of skill. Accordingly, the estimated skill percentile for this profile is 98.00th percentile.

Note: Mario Kart 8 on Wii U remains one of the best online multiplayer experiences I’ve ever had. From tracks like Sunshine Airport and Toad Harbor to Rainbow Road (SNES & N64), the game offered one classic after another—both in racing and soundtrack quality. I recall late-night sessions, often in lobbies packed with Japanese players racing before work. Snagging 1st place in those games and seeing my country’s flag at the top, surrounded by Japanese flags, was a satisfying reminder of the global passion and competitive spirit that fuels the game.

Mario Kart 8 Deluxe (2017) NSW, 1st Place All 150cc Cups (Unknown Clear Rate)

Mario Kart 8 Deluxe (2017)

Similar to its Wii U predecessor, achieving first place in all 150cc Grand Prix cups in Mario Kart 8 Deluxe—despite the absence of precise clear rate data—constitutes a high-skill accomplishment. Consistently securing top placements across all tracks requires mastery of key mechanics, including advanced track memorization, optimal item management, and the strategic use of gap-building techniques against adaptive AI opponents. These elements collectively demand sustained precision and decision-making over a wide variety of course types and race conditions. Given the comparable level of difficulty to the Wii U version, the estimated skill percentile for this achievement is assessed at 98.00th percentile.

Note: Personally, I preferred Mario Kart 8 on Wii U over Deluxe on Switch—fire hopping just felt more satisfying and added a unique layer of depth. I didn’t spend much time with 200cc in MK8D either; the speed was exhilarating, but drifting felt awkward on the thumb. As for the DLC tracks? They were okay, but nothing that topped the base game's lineup for me.

Ape Escape 3 (2005) PS2, 100% (5.94% Clear Rate)

Ape Escape 3 (2005)

The individual achieved 100% completion in Ape Escape 3, corresponding to a reported clear rate of 5.94%. Full completion in this title entails capturing all 442 monkeys and acquiring every in-game collectible, including items, CDs, video tapes, and car skins. This comprehensive task reflects a high level of persistence, system mastery, and attention to detail. The game’s completion criteria are notably described as being tailored for “the obsessive gamer who likes to complete 100 percent of the game,” underscoring the rarity and intensity of the effort involved. The reported 5.94% clear rate is accepted as an accurate representation of the rarity of this achievement. Accordingly, the estimated skill percentile for Ape Escape 3 is 94.06th percentile.

Note: This was the first “anime” game I ever owned as a kid, and it totally sold me on that clean, cartoony anime art style. To this day, I still wish more games looked like Ape Escape 3. We need Ape Escape 4—badly.

GTA IV (2008) PC, Main Story (7.8% Clear Rate)

Niko Bellic featuring prominently in front of the Algonquin Bridge.

The individual completed the main storyline of Grand Theft Auto IV on PC, corresponding to a reported clear rate of 7.8%. This value is consistent with Steam achievement data, which shows that only 7.1% of users completed the final mission. The relatively low completion rate for main narratives in expansive open-world games such as GTA IV is a well-established pattern, typically attributed to players becoming absorbed in side content or discontinuing engagement with long-form campaigns. Nevertheless, completion of the primary storyline signifies a sustained commitment and a level of progression achieved by a limited subset of the overall player population. Accordingly, the estimated skill percentile for GTA IV is 92.20th percentile.

Note: I was genuinely surprised to see that only around 7–8% of players finished the main story in GTA IV. I would’ve guessed at least 20–25%. It’s one of the more grounded and well-written campaigns in the franchise—definitely worth finishing.

Ridge Racer R4 (1999) PS1, Main Grand Prix Micro Mouse Mappy Team (8.2% Clear Rate)

Ridge Racer R4 (1999)

The individual completed the Main Grand Prix using the Micro Mouse Mappy team in Ridge Racer Type 4, with a reported clear rate of 8.2%. Data from RetroAchievements for comparable Grand Prix completions—such as the “Easy Grand Prix” with the same team—indicate higher clear rates (e.g., 19.71% and 14.39% for certain no-repeat conditions). The lower reported rate of 8.2% therefore likely corresponds to a more demanding progression path or reflects a more accurate aggregated completion rate for that specific team and difficulty combination. Given the technical handling demands and unique driving style required by the Micro Mouse Mappy vehicles, this accomplishment signifies both precision and adaptability. The estimated skill percentile for this achievement is 91.80th percentile.

I Note: I first played this on the PlayStation Classic. Tight controls, smooth drifts — a genuinely nice game that holds up well even today.


Methodology for Composite Gamer Percentile Estimation

To derive an overall "gamer skill percentile" from a diverse portfolio of achievements, a mathematically robust aggregation technique is required. A simple arithmetic mean of individual percentiles risks distortion, especially when dealing with skewed distributions or rare achievements. Instead, a geometric mean approach is used, which better captures the combined rarity of multiple independent accomplishments.

Each achievement percentile 𝑝𝑖 is first converted into a rarity factor, calculated as:

rarity factor r_i = 1 − (p_i / 100)

The geometric mean of these rarity factors across all N achievements is then calculated as the N-th root of the product of all rarity factors:

geometric mean rarity = (r_1 × r_2 × ... × r_N) ^ (1/N)

The overall gamer skill percentile is obtained by subtracting this geometric mean rarity from 1:

overall percentile = 1 − geometric mean rarity

In this analysis, equal weighting is applied to each achievement, emphasizing the subject’s broad mastery across multiple game genres rather than focusing on any single title or player base size.

For example, with 24 individual achievements and their respective rarity factors (converted from percentiles), the product of all rarity factors is approximately 2.62 × 10^(-47). Taking the 24th root (i.e., raising this product to the power of 1/24) yields roughly 0.0107. Subtracting this from 1 gives an overall gamer skill percentile of approximately 0.9893, or 98.93%.

This means the individual performs better than approximately 98.93% of the global gaming population, confirming elite status. Moreover, the extraordinarily low product of rarity factors implies that the probability of a single person independently achieving this exact combination of accomplishments is effectively zero—about 1.06 × 10^(-47)—highlighting the exceptional nature of this "polymath gamer."

Proposed System: GAMMA (Generalized Achievement Metric for Multigenre Aptitude)

Despite decades of innovation in competitive gaming, achievement tracking, and performance analytics, there remains no standardized framework for quantifying general gaming proficiency across genres. Existing systems—such as Elo, Glicko, or MMR—are narrowly scoped to PvP ecosystems and fail to capture the cognitive, motor, and strategic demands of single-player accomplishments, genre diversity, or non-competitive feats.

We propose GAMMA (Generalized Achievement Metric for Multigenre Aptitude) as a foundational step toward filling this gap: a mathematically grounded, genre-agnostic rating system that assigns persistent skill ratings based on the rarity, difficulty, and credibility of a player's cleared objectives across all game types. By treating performance in each title as a probabilistic signal—weighted by community-vetted data sources such as global clear rates, leaderboards, and verified tournament results—GAMMA allows for the synthesis of a unified skill metric that reflects cross-domain mastery.

To our knowledge, no formal system currently exists that rigorously models the combinatorial and cognitive complexity of multigenre gaming excellence. GAMMA therefore represents a conceptual leap forward: an attempt to bridge the fragmented and siloed structure of modern gaming into a coherent statistical framework capable of identifying and ranking true polymathic ability in interactive digital environments.

To the best of my knowledge, there is no unified, mathematically rigorous system that measures general gaming aptitude across genres using verified achievements, clear rate rarity, and weighted difficulty. If such a system is ever fully realized — GAMMA may stand as the conceptual prototype that began it.

Conclusion: A Legacy of Gaming Excellence

This comprehensive statistical analysis highlights the extraordinary nature of the individual’s gaming profile. With an estimated overall gamer skill percentile of 98.93%, the subject is positioned within the elite top tier of players across a remarkably diverse array of gaming genres. The vanishingly small probability—approximately 1.06 × 10⁻⁴⁷—of any single individual independently achieving this precise constellation of elite accomplishments underscores the profound rarity of this polymathic gaming aptitude.

The achievements outlined herein—from dominating competitive multiplayer arenas with exceptional kill/death ratios and consistent MVP-level performance, to conquering notoriously difficult single-player campaigns without reliance on exploits, setting competitive speedrun benchmarks, and attaining comprehensive 100% completions—collectively portray a gamer whose expertise transcends individual titles. This profile reflects a core, transferable gaming intelligence characterized by superior learning agility, adaptive strategic thinking, and peak execution across fundamentally different mechanical and cognitive demands.

More than a mere aggregation of statistical feats, this profile stands as a testament to exceptional dedication, strategic acumen, and enduring passion for gaming. The individual exemplifies a rare archetype of gaming excellence, prompting deeper consideration of the multidimensional nature of skill and the extraordinary heights achievable within the gaming ecosystem.

The purpose of this exercise was to show that the insights shared on this blog are grounded in genuine skill and firsthand experience—not just empty claims.

While I firmly believe I rank in the top 1–1.07% for several games I’m truly passionate about, a more realistic overall estimate would likely place me around the top 3–5% of gamers worldwide, given the wide variety of genres and skills involved.

Gaming is a lifelong journey of growth and discovery, and I’m excited to keep pushing my limits and sharing that experience with this community.
