Old School RuneScape

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.

Old School RuneScape is a well-known fantasy MMORPG from Jagex, released in 2013. It maintains a strong persistent player base due to nostalgia, consistent updates, and mobile availability. Although past its peak, it still regularly draws tens of thousands of daily active players across all platforms. Estimates in recent years place its daily active player count between 70,000–120,000, so 90,000 is a conservative current estimate.
