C21: Steel Battle Chronicles

VS

Scum

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.

Scum is a multiplayer open-world survival game developed by Gamepires and originally entered Early Access in 2018. While it is not a full MMO, it supports servers with dozens of players (up to 64 per server). The game maintains a niche but dedicated following and is frequently updated; however, it has never reached large mainstream status. Based on long-term trends of similar survival games, its daily active player base is estimated to be in the low thousands, and this estimate would hold unless a major relaunch or expansion revitalized the player base.
