Ark: Survival Evolved

Perpetuum is an indie sci-fi MMO released in 2014 by Avatar Creations. It featured persistent world mechanics and large-scale multiplayer, aligning with MMO definitions. The game struggled to keep a sizable population over time and was officially shut down by its developers in 2018. Any current activity stems from community-run servers, which have very low daily player numbers (likely below 100).

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.
