Evolution Worlds is a Nintendo Gamecube RPG created by Sting Entertainment. It was a compilation of Evolution: World of Sacred Device and Evolution 2: Far Off Promise, two previous Sega Dreamcast games, and merged the two together for the Gamecube release. The game is unique in that it's a combination of a regular RPG and a Roguelike, with randomly-generated dungeons, stairs, and traps, but with a standard RPG battle system; you can level up skills in midbattle by spending TP on a wide range of movepools.
