Block Story

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.

Block Story is an indie sandbox RPG released in 2015, somewhat inspired by Minecraft but with RPG and adventure elements. Its initial popularity has significantly declined over the years due to its age, lack of major developer presence, and limited mainstream attention. As an older indie title with mainly single-player or small-scale multiplayer features, it now likely retains a very small, dedicated player base across platforms.
