The Mana World

VS

Roblox

The Mana World is an open-source, community-driven MMORPG first released in 2004. Given its age, lack of a major publisher or recent major updates, and its niche free software nature, its player base is very small. Typical estimates for similar older open-source projects suggest daily active players in the low hundreds or less. It meets MMO criteria as it has a persistent world and supports large-scale multiplayer interaction.

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.
