Vendetta 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.

Vendetta Online is an indie space MMO launched in 2004. It features a persistent universe, cross-platform play, and niche yet dedicated playerbase. Due to its age and limited mainstream attention in recent years, daily active players are estimated to be very low, well under 1,000 daily. However, its MMO mechanics and persistent world justify the MMO label.
