Citadel: Forged With Fire

VS

Scum

Citadel: Forged With Fire is a multiplayer sandbox RPG that launched in 2019. It peaked with modest interest but has seen steep declines due to limited long-term updates, smaller indie studio support, and competition in the survival/fantasy sandbox genre. Current player populations are very low, with estimates typically under a few hundred daily. It does feature persistent world elements and can be considered an MMO, albeit with relatively small servers compared to major MMO titles.

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.
