I got a Mac, PS2 and Gamecube but hardly ever use my consoles cos my GF kicks off when I leave them setup on the TV downstairs, I think I'm gonna have to get a 21" telly upstairs
Anyways I'm really looking forward to GT4 when it actually gets released as I love driving games.
My Fav list of games have to be:
Sensible Soccer (Amiga)
Gran Turismo 1,2,3 (Ps & Ps2)
Unreal Tournament 2003 (Mac)
Mario Kart Series (Nintendo's)
Street Fight 2 Turbo (SNES)
This are the ones I can think of but I'll update as I remember
