Now that GCs life is almost done I went ahead and made a list of what I think are the top ten hardest to find GC games:

Bust-A-Move 3000
Disney Extreme Sports Basketball
Disney Extreme Sports Football
Disney Extreme Sports Skateboarding
Disney Extreme Sports Soccer
F1 2002
Goblin Commander: Unlease The Horde
NCAA College Basketball 2k3
Pokemon Box
Rave Master

With NCAA being the hardest to find

Thoughts?
