Path of Exile is a well-known free-to-play action RPG by Grinding Gear Games. While 'Betrayal' refers to a specific major expansion released in 2018, Path of Exile itself is still supported and hosts regular leagues and updates, though Betrayal content is now folded into the core game. Daily active players have declined from their peak, but with ongoing seasonal content, it likely sustains around 50,000 daily active players across all platforms as of 2024.
