Wii - Super Paper Mario, The Legend of Zelda: Twilight Princess... Soon to get: Wario Ware: Smooth Moves, Super Mario Galaxy, Super Smash Bros. Brawl, Mario Kart: Double Dash!!
Xbox 360 - Marble Blast Ultra (arcade game), Project Gotham Racing 3... Soon to get: Banjo Kazooie 3, Halo 3.
Playstation 3 - ... Soon to get: Gran Turismo 5, Ratchet and Clank: Up Your Arsenal, and maybe... Little Big World... If it's not too childish...
I don't own a single game for the Playstation 3, thanks to Sonic the Hedgehog. Thank you Sonic, for wasting my $80, getting rid of you, and never buying another Playstation 3 game... Ever again!
