Space Station 13

Roblox is a massively popular sandbox platform, released in 2006 but continually updated and widely adopted by younger audiences globally. It consistently reports tens of millions of monthly active users, with peak daily actives usually around 5–10% of monthly users. Recent filings and reports indicate Roblox has over 60 million daily active users, but this covers global user logins across many devices and experiences. Adjusting conservatively for reporting and engagement variance, daily actives typically exceed 50 million worldwide, but simultaneous users generally peak in the hundreds of thousands to low millions. As a platform with persistent worlds, it fits the broader MMO definition.

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.
