The Mana World

Goose Goose Duck

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.

Goose Goose Duck is a social deduction party game released in 2021, similar to Among Us, which had significant popularity during its first year and retains an active global player base, particularly in regions like Asia. However, being a party game, player retention over time is moderate but not at massive scales seen in major MMOs, though it holds steady with tens of thousands of daily active players two years post-launch.
