R2 Online: Reign of Revolution

VS

Scum

R2 Online: Reign of Revolution was developed and published by Webzen, an established South Korean MMO publisher, and originally launched in the late 2000s. As an older Korean MMORPG targeting mostly the South Korean market, it's well past its initial peak and sustains a small but stable, loyal base on its home servers. Limited Western exposure and age suggest current daily active players are in the low thousands.

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.
