shooting games (touhou, Ikaruga), RTS/TBS, RPG(not final fantasy or like) more like Mass effect or Fate stay night, aka for the storytelling not the lving. Games with pretty colors to rythems (elite beat agents, Stepmania,DDR, In the groove, Guitar hero, and many many more).
I also like fighting games for the community aka not filled with 12 year olds that only know the word n00b and don't understand that helping is nice aka what has happened to starcraft, warcraft III, halo 3 and begining to happen to COD4, and all other popular multiplayer games, at least in fighting games you can just beat the living shit out of them all day (lol), as long as its 2D, 3D's are a little easier to win a round or 2.
