Somnium Space VR

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.

Somnium Space VR is a niche open-world social VR platform focused on virtual real estate and metaverse experiences. Its daily player base is relatively small due to its specialized audience and limited mainstream adoption compared to larger VR worlds. The game supports persistent social environments, aligning it with MMO definitions, but its overall user base remains limited.
