Roblox

Second Galaxy is a space-themed open world sandbox RPG, released in 2019 by ZLongame. It attracted some attention as a mobile and PC MMO with large-scale battles and persistent universe features similar to EVE Online but with broader accessibility. As a 4+ year-old game from a mid-tier publisher, its audience has likely contracted, but persistent sandbox gameplay tends to retain a modest core. Estimated at ~20,000 DAP based on aging lifecycle and competitive genre.

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.
