Towards Handicapping for Online Competitive Video Games: A Taxonomical Review of Intervention Studies

Summary
The paper addresses how skill disparities in online competitive video games create a "playerbase-diminishing feedback effect": weaker players suffer repeated defeats and quit, leaving the next tier to become the new bottom — a cycle that ultimately restricts access to only the most dedicated, skilled players. The authors argue that while skill-based matchmaking (SBMM) is the default industry response, it cannot serve populations with sparse skill distributions or newcomers entering far below the population skill floor. Drawing parallels with handicapping in golf, horse racing, archery, and para-athletics, they propose that handicapping mechanisms — asymmetric adjustments for one or both competitors — are an under-used tool in video games. The paper's central contribution is a novel taxonomy that classifies handicapping mechanisms by the degree to which each player contingent experiences "representative" gameplay conditions (i.e., the actions and states available under non-handicapped play). Four types emerge: Type-rN (neither player experiences representative conditions, e.g. rubber-banding); Type-rS (only the stronger player, e.g. concealed aim-assist for the weaker player); Type-rW (only the weaker player, e.g. capping the stronger player's abilities); and Type-rA (both experience representative conditions, e.g. score handicaps). A systematic review across four academic databases identifies ten peer-reviewed intervention studies spanning FPS, racing, light-gun, and third-person shooter genres; each mechanism is classified against the taxonomy and its reported balancing and enjoyment outcomes synthesised.
Key findings
Across the ten reviewed studies, handicapping mechanisms generally succeeded at narrowing score gaps between mixed-ability opponents and did not diminish player enjoyment — often enhancing it, particularly for weaker players. Hybrid mechanisms that manipulated multiple gameplay elements (e.g., combining aim-assist with damage adjustment and spatial awareness cues) outperformed single-element interventions. The long-standing assumption that handicapping must be concealed to preserve fairness was contradicted: disclosure did not reduce enjoyment, and in several studies awareness improved feelings of competence and flow, with players expressing a preference for transparency and agency. Crucially, the taxonomy revealed a lopsided research landscape: of 27 classified mechanisms, 18 were Type-rN, 8 were Type-rS, only 1 was Type-rW, and zero were Type-rA. No study has yet implemented handicapping that preserves authentic gameplay conditions for both players (Type-rA), despite this being the normal approach in sports. Additional findings: well-calibrated static mechanisms may outperform dynamic "trailing score" systems on engagement; aim-assist alone is insufficient to balance complex FPS play; and longitudinal evidence refutes the "guidance hypothesis" that assistance stunts long-term skill acquisition.
Relevance
While framed around video game balance, the paper's arguments are directly relevant to accessibility practitioners. The authors explicitly connect handicapping to game accessibility, citing disability, low-end hardware, and work-life constraints as causes of apparent ability differences that exclude players from competitive ecosystems — and from the associated labour opportunities in esports, game development, and content creation. Their "access pathway" model proposes that handicapping types can scaffold progression from tutorial competence through operational competence to the population skill floor, offering an inclusion route where SBMM fails. For accessibility teams working on gaming platforms, the taxonomy gives a concrete framework for evaluating assistive features (aim-assist, auto-aim, damage scaling, score handicaps) against perceived fairness, stigma, and player agency. Limitations include a small corpus (n=10) heavily weighted toward FPS and racing, with no coverage of MOBAs or fighting games — genres the authors flag as priorities for follow-up work.
