Evoland (PC, Mac)
Recently accepted by Steam Greenlight, Evoland is an RPG with the unique hook that the graphics and gameplay evolve as you play. Beginning with a monochromatic Gameboy Zelda-style adventure, you play through and discover the emergence of JRPG active battle systems, and, eventually, fully 3D dungeons with modern real-time combat. It helps that throughout it all, the art looks to be superb, and the music is already proving to be fantastic.
Oh, this looks cool!
whaaaaaaaaaa?! what a cool concept!
