Space Station 13

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.

Space Station 13 is a cult classic sandbox multiplayer game originally released in 2003, with various community servers running different versions. Despite its age, it maintains a small but active playerbase due to its unique gameplay and strong, niche community. Across all servers and codebases, the estimated daily player count ranges from 2,000–5,000, so approximately 4,000 daily players is a reasonable estimate in 2024.
