I have a huge Gamecube wishlist of stuff that's already out, but I won't worry about those. Anyways-
GC:
Pikmin 2
Paper Mario 2
Metroid Prime 2
Geist
Starcraft: Ghost
*New* Legend of Zelda
Also, my bro is going to need to buy a PS2 so we can get Dragon Warrior 8
EDIT: Oh yeah, and aside from all games... the DS! We are going to need to get a DS and a good few titles. So many things, so little money!
