Old School RuneScape

Sword Art Online: Integral Factor is a mobile and PC action RPG published by Bandai Namco, released in 2018. While it had popularity in its first years—especially among SAO anime fans—player base has declined over time due to lack of major updates and competition in the mobile RPG space. Still, it retains a steady niche audience, particularly in Asia. Estimate: 35,000 daily players.

Old School RuneScape is a well-known fantasy MMORPG from Jagex, released in 2013. It maintains a strong persistent player base due to nostalgia, consistent updates, and mobile availability. Although past its peak, it still regularly draws tens of thousands of daily active players across all platforms. Estimates in recent years place its daily active player count between 70,000–120,000, so 90,000 is a conservative current estimate.
