Star Citizen

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.

Star Citizen is a highly ambitious, persistent online sci-fi universe developed by Cloud Imperium Games and in development since 2013. The game maintains strong interest due to continuous updates and community engagement, though it's still in alpha. Its daily active players generally range from 30,000 to 60,000, despite being niche compared to mainstream MMOs, but with a loyal playerbase and steady developer communication.
