Bit Heroes

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.

Bit Heroes is a 2016 retro-style RPG published by Kongregate and available on multiple platforms. While not a mainstream success, it maintains a dedicated niche audience due to its continuous updates and mobile appeal. As a midlife F2P online RPG, it's likely to have a modest but stable daily active user base in the low five figures. However, its core gameplay does not support a true persistent, large-scale world with hundreds interacting live, so it is not a traditional MMO.
