World War II Online

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.

World War II Online is a veteran MMOFPS released in 2001, notable for its massively multiplayer persistent battlefields and niche but dedicated community. Due to its age, ongoing but modest support from the developer, and consistently niche audience, the daily player count is likely around several hundred.
