Marvel Future Revolution

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.

Marvel Future Revolution, released in 2021 by Netmarble, is a mobile open-world RPG with action elements. While it launched with strong brand power (Marvel) and decent initial popularity, its player base has declined significantly due to standard mobile MMO lifecycle trends and limited recent updates. The game is still live, but community and industry sources suggest a small remaining player base, likely around 5,000 daily active players.
