I disagree:
1. How could the GameCube be the odd one out with huge hits like Super Smash Bros. Melee, Animal Crossing, Resident Evil 4, Metroid Prime, F-Zero GX, Star Wars Rogue Squadron II, and all of the Zelda and Mario games (Golf, Tennis, Strikers, Party, Sunshine, etc.)?
2. GameCube games have some of the quickest load times I've ever seen.
3. I think the design of the GameCube will age better than that of the Xbox. I always found the Xbox to be cheap looking. Maybe it's the glossy black plastic that gets scratched too easily. It's also far too large.
4. The GameCube is more durable.

5. The GameCube had the best version of Soulcalibur II.
6. Beach Spikers is far better than Dead or Alive Xtreme Beach Volleyball.
7. Kabuki Warriors.
