Roblox

PixArk is a voxel-based survival game released in 2018 by Snail Games. It is a spin-off of ARK: Survival Evolved with co-op and multiplayer features, but lacks the persistent large-scale world typical of MMOs. The game saw moderate initial interest but has a very modest player base today, as most survival games experience sharp population declines after several years unless they have strong ongoing support or a dedicated community.

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.
