Rage:MP

VS

Scum

Rage:MP is a multiplayer modification framework for Grand Theft Auto V, allowing the creation and play of custom servers. While it enables large persistent worlds reminiscent of MMO environments, the game itself serves as a platform for such content rather than operating as an MMO in the traditional sense. Daily activity fluctuates; as of 2024, the player base is stable but niche, mostly centered around roleplay servers, which can attract thousands at peak times, but the overall daily active user base is modest compared to mainstream MMOs or GTA Online itself.

Scum is a multiplayer open-world survival game developed by Gamepires and originally entered Early Access in 2018. While it is not a full MMO, it supports servers with dozens of players (up to 64 per server). The game maintains a niche but dedicated following and is frequently updated; however, it has never reached large mainstream status. Based on long-term trends of similar survival games, its daily active player base is estimated to be in the low thousands, and this estimate would hold unless a major relaunch or expansion revitalized the player base.
