Book of Demons

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.

Book of Demons is a single-player or limited multiplayer hack-and-slash action RPG released in 2018 by indie developer Thing Trunk. The game appeals to a niche audience and, given its age, likely retains only a small but dedicated player base. It is not supported by major expansions or large-scale online features.
