Scum

Florr.io is a browser-based indie action game released in 2020 by Matheus Valadares, known for creating other successful io games like diep.io and agar.io. While past io games had massive player spikes, Florr.io's current active player base is significantly lower given its age, niche appeal, and the general decline of the io genre after their peak, but it maintains a dedicated community. A conservative estimate considering ongoing casual traffic is about 10,000–20,000 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.
