Re: What are good GameCube games?
Almost every first party game on the Cube is worth checking out. My personal favourites were Zelda (I loved the cell shaded graphics, I don't understand why people hated it so much, also Twilight Princess can be found on the Cube and that is arguably the best game I have ever played), Super Mario Sunshine (again, many people thought it sucked, I loved it although Galaxy is waaay better), both Metroid Primes (awesome action/adventure games, huge fan even though I can't stand "science fiction"), Mario Kart Double Dash (multiplayer madness!), Metal Gear Solid: Twin Snakes (fantastic remake of the first MGS)...
The Cube was a good system, but there were too few good games. However, the Wii is suffering the same problem.
