Star Wars: Rogue Squadron 2: Rogue Leader
A Gamecube launch game that still looks better than most Wii games. I also still have a blast playing the second to last level with hundreds of Tie Fighters swarming you.
Current systems owned: Wii, 360. I'll get a PS3 when hell freezes over!... or when the price drops to a reasonable level. Whichever comes first.
