PS2 or GCN? I know the gameplay is the same, but I want to know about the controls.

The controls are pretty similar I think... I got the PS2 version. Only think I liked was the MMX8 trial version, XD

Either way it's pretty much the exact same thing. But as MMX8 is old old stuff, you could go for GameCube if you want to do some... trophy thing I think with the GBA connector.

The Trophy Map? Then I'd have to get a GBA, and a Cable, and a game... But it's worth it. I'll buy it after I pay off my ramen tab.
