Hmm, this is a controversial choice for me. I mean,. there are plenty of oldschool games I love, like SuperMario World, the DKC series, Sonic 3 & Knucles, Dynamite Headdy, etc, but new school has Banjo-Kazooie, SM64 (I count them as new school, since there both 3D platformers), GbtG, Halo and it's sequal, Metroid Prime, Shadow of the Collossus, etc. Well, since I certainly don't want to say "Gamecube is better than NES", I guess I'll pick oldschool
