Wurm Unlimited

Roblox

Wurm Unlimited is a standalone version of the sandbox MMO 'Wurm Online,' letting players host private servers or join others. Released in 2015 and with a niche but dedicated community, it has seen declining but stable activity, primarily among small private servers and modding enthusiasts. As a sandbox MMO with player-run worlds but no central persistent world like Wurm Online, its active playerbase is limited but consistent, likely under 500 daily.

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.
