Arghh too many to list, I'll boil it down for you. Most Nintendo games on the NES, SNES, N64, GC, and Wii with exceptions like Mario 64, Tennis, Paper Mario, Metroid Prime, Super Mario World, etc. every Valve game except Portal, most of Sony's newer and older games, every Microsoft game, and probably a ton of iconic PC games like Doom for example. It's not that I don't want to play these games is just that I don't have the time at the moment to play them all. They are on my bucket list of games to get though, so the time will come.
