The main page on this site just showed the highest ranked Gamecube games:
SSB Melee
Twilight Princess
Resident Evil 4
Metroid Prime
Mario Strikers
F-Zero GX
Wind Waker
MP Echoes
Pikmin 2
Mario Sunshine
It put a smile on my face remembering my enjoyment of 8 out of 10 of those games (I don't own RE4 or Strikers).
