Ark: Survival Evolved

C21: Steel Battle Chronicles is an online action RPG from CyberStep released in 2006. Given its age (over 15 years), niche publisher, and the lack of widespread recognition outside of Japan, it is likely to have a very small but dedicated player base. Its live services seem primarily targeted at a Japanese audience. Unless supported by recent re-releases or major updates, games of this profile generally retain a few hundred to a few thousand daily players.

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.
