Roblox

Hurricane.io is a browser and mobile 'io' game released in 2017. These types of games generally have modest, short session-based multiplayer rather than persistent worlds. The game is relatively old for the io genre, which suffers player declines as newer games emerge. Given its age, indie origins, and modest current online presence, an approximate daily active player count would be around 2,000. It is not a true MMO, as it lacks a persistent, large-scale world.

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.
