Legends of IdleOn

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.

Legends of IdleOn is a well-known idle MMORPG created by indie developer LavaFlame2, released in late 2020 and available on multiple platforms (PC, Android, iOS). While it is not developed by a major studio, the game has remained popular within its niche, fueled by regular content updates and a dedicated player community. Given its cross-platform support, ongoing development, and its distinct idle MMO format, a daily player count in the 25,000–40,000 range is typical for active indie MMOs of this scope about 3-4 years after launch.
