Summoners War: Sky Arena

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.

Summoners War: Sky Arena is a long-running and successful mobile RPG released in 2014 by Com2uS. Despite being nearly a decade old, it maintains a solid player base due to regular updates, global events, and a competitive PvP scene typical of well-supported mobile gacha RPGs. While it is not at its peak, it likely still achieves around 100,000 daily active players, especially across multiple regions and platforms.
