Achaea, Dreams of Divine Lands VS Infinity: Battlescape

Achaea, Dreams of Divine Lands is a classic text-based MUD (Multi-User Dungeon) released in 1997. While it has a long-running, dedicated community and is supported by Iron Realms Entertainment, the active daily player base for such niche, text-based MMOs is generally small—typically in the low hundreds. It maintains a persistent world and large-scale multiplayer features, qualifying it as an MMO.

Infinity: Battlescape is a space combat simulator released in 2019 by the indie developer I-Novae Studios. Despite its unique large-scale space battles and ambitious scope, the game did not achieve mainstream popularity and shows signs of a small but dedicated community. As an indie game with limited updates and publicity, it's likely to have a very low daily active player base, estimated around 50. The game features large battles but does not have a true persistent world, so it is not considered a full MMO.
