Grand Chase

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.

Grand Chase is a well-known side-scrolling action MMORPG originally developed by KOG Studios. Although the classic PC version was shut down in most regions years ago, the mobile relaunch (Grand Chase: Dimensional Chaser) and a Steam version have seen some limited success since 2017. Due to its age, niche appeal, and relatively modest marketing outside its core market (primarily Southeast Asia and Latin America), I estimate its daily active player base to be low thousands. The game does have persistent multiplayer elements and instanced co-op/competitive modes, qualifying as an MMO.
