Marbles on Stream

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.

Marbles on Stream is a viewer-interactive racing and simulation game popular with Twitch streamers. While it saw peak activity shortly after launch (2018), its player base is now niche, sustained mainly by streamers and their communities. As it does not generally attract large independent play outside streaming events, estimated daily active players are modest, usually in the low thousands.
