If you could choose the Retro courses for the next Mario Kart...

[arsenal009]

Yoshi Valley N64
Bowser Castle snes (i think there is more than 1, so any one)
Koopa beach snes
Donkey Kong N64 again (my fav track)
Rainbow road snes
Ghost Valley snes (the one that wasn't in MK Wii)

and make all the snes tracks 5 laps not 3
