Except for the C-stick issues that Nanner mentioned, I thought Ocarina of Time worked just as well on GameCube as it did on N64. Honestly, the C-stick only bothered me on the ocarina to a small extent. For my items, I always used it rather than X, Y, and Z. They just didn't feel like the game to me.

In other news, I just bought Mario & Luigi: Superstar Saga today, and I think it's great. After years of watching the cartoons, they finally made a game that shows the Mario Bros. (whatever happened to the Bros., huh?) working together! Anybody else ever play this?
