Enlisted

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.

Enlisted is a free-to-play squad-based World War II shooter developed by Darkflow Software and published by Gaijin Entertainment. Launched in 2020 and available on multiple platforms, its player base is supported by ongoing updates and events promoted by Gaijin. However, as a niche shooter (and not a top-tier AAA franchise), its daily active players likely peak in the tens of thousands, not hundreds of thousands. The game has moderate popularity among enthusiasts of realistic shooters but does not reach the scale of major titles like War Thunder or Battlefield. Players per match are capped and it lacks the persistent world of a true MMO.
