Cluster

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.

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.
