I'm more of a console game lover. Mainly Nintendo games though but I have a few that aren't.
Playstation 2: Kingdom Hearts 1&2 also the entire DDR series. Did anyone else go through the DDR phase?
N64: Mario 64, Legend of Zelda Marjora's Mask, Pokemon Stadium
GameCube: Pikman, my entire Legend of Zelda Collector's Edition box set of every Zelda game, Mario Kart DoubleDash.
Wii: (wii kinda sucks) Mario Kart, Legend of Zelda Twilight Princess and Skyword Sword.
Xbox360: The Assassin's Creed series, Last Remnant, Tales Of Vesperia. I also have a guilty pleasure of playing Dance Central.
