FiveM

Ark: Survival Evolved is a popular survival sandbox game released in 2017 and available on nearly all platforms. Its peak was several years ago, but it maintains a stable community thanks to official and community servers, modding, and occasional event content. While numbers have declined since launch, the game still sees tens of thousands of daily players across PC and consoles, especially due to its ongoing updates and active mod scene. However, it is not an MMO as it does not feature a single, large-scale persistent world—servers are capped and players are sharded.

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.
