How is Forza? I don't have an XBox, I tried the demo for 10 minutes at a store once and it was pretty cool. And I'm a pretty big fan of Gran Turismo, it seemed like the same sort of game to me.
My collection of consoles(chronologically):
Genesis(not anymore, it was given away

)
Gameboy(original model, with transparent casing 'Play it Loud' deal they had going on)
Gameboy Color(Purple, I think)
Nintendo 64(my favorite)
Gameboy Advance(original with dark screen, in purple because the other colors were sold out when I got it

)
Gamecube(excellent hardware, it's unfortunate it wasn't more popular with developers)
Playstation 2(hardware is opposite of Gamecube, it's falling apart, yet everyone loves to make games for this technology disaster

)
DS(games aren't nearly as good as the GBA, I'm not a huge fan, really)
