Firestone: Online Idle RPG

Scum

Firestone: Online Idle RPG is a cross-platform idle RPG released in 2021 by indie studio HolyDay Studios. Although it has active support and an online component, it appeals to a niche audience typical of idle RPGs, and has seen moderate long-term retention, likely resulting in a few thousand daily players primarily via browser and mobile platforms.

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.
