Arma II: DayZ

VS

Roblox

Arma II: DayZ was a highly influential mod released in 2012 that sparked the survival multiplayer trend. Over ten years old and supplanted by the standalone 'DayZ' game, the original Arma II mod now has a very small, niche player base, primarily devoted fans. Daily active players are likely in the low hundreds.

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.
