Aardwolf MUD

Roblox

Aardwolf MUD is a long-running text-based MUD (Multi-User Dungeon) with a persistent world, released in 1996. While niche, it remains one of the more active MUDs due to a loyal community and continuous updates. However, player numbers are modest due to the genre's age and obscurity, with typical daily active users likely in the low hundreds.

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.
