GGTech Studios

This game has been free on Steam for over a year, but the devs say they have to charge $4 now because "keeping the servers active indefinitely requires covering costs"

GGTech Studios is changing its free-to-play multiplayer platformer eWorlds to a premium model, charging $3.99 to cover ongoing server costs. The transition comes over a year after the game's initial free release on Steam. The developers state this change is necessary for the long-term sustainability and growth of the game.
