Aabahran: The Forsaken Lands

VS

FiveM

Aabahran: The Forsaken Lands is a very old text-based MUD (Multi-User Dungeon), launching in 2000. MUDs generally have niche, loyal communities but extremely low player counts after two decades. Although it has multi-platform support and a Facebook presence, its age and lack of major publisher support mean its daily active population is likely under 100, with only a handful of dedicated players remaining.

FiveM, released in 2016, is a popular modification framework for Grand Theft Auto V that enables custom multiplayer servers, especially for roleplay communities. Its active modding scene and the enduring popularity of GTA V have kept its playerbase strong, typically with hundreds of thousands of daily players. However, it's technically not an MMO as individual servers usually host dozens to a few hundred players, not a persistent shared world for thousands.
