EOMM in Marvel Rivals stands for Engagement Optimized Matchmaking. It is a matchmaking system designed to maximize player retention and engagement rather than strictly matching players based on skill or fairness. The idea behind EOMM is to keep players emotionally engaged by managing win/loss streaks. If a player is on a losing streak, EOMM might give easier opponents and stronger teammates to prevent the player from quitting. Conversely, if a player is winning too much, the system might increase difficulty by matching them against better players or giving them weaker teammates to keep the challenge. This can lead to inconsistent match difficulty and match outcomes seemingly manipulated to maintain player interest. However, the developers of Marvel Rivals, NetEase, have officially stated that the game does not use EOMM. They acknowledged community concerns about matchmaking and promised to release a video explaining their matchmaking system and ranking mechanics. Despite this, many players remain skeptical, noticing patterns such as forced win/loss streaks and unbalanced teams that fuel the belief that some form of EOMM or a similar engagement-optimized system is in use. In summary, while EOMM is a known concept aiming to optimize player engagement by controlling match difficulty dynamically based on player behavior and streaks, Marvel Rivals' official position is that it does not use this matchmaking system. Nonetheless, player experiences and community discussions suggest matchmaking might have elements that resemble EOMM principles, causing ongoing debate and dissatisfaction in the player base. EOMM is distinct from traditional skill- based matchmaking, focusing more on player retention through emotional engagement rather than pure competitive fairness. This matchmaking controversy has been widely discussed among Marvel Rivals players, including accusations of manipulated match outcomes and uneven matchmaking that affect the game's competitive integrity and enjoyment.
