Scum

Cluster is a Japanese-developed social VR/metaverse platform that has been steadily growing, especially in Japan. While not as globally popular as VRChat, it hosts regular events, boasts cross-platform support, and targets the growing social simulation/metaverse niche. Player engagement is concentrated in Japan and East Asia, with daily active users estimated between 5,000 and 15,000. The platform supports persistent worlds and large multiplayer events, although it's not as ubiquitous as its larger VR/metaverse peers.

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.
