I didn't seem to be too bothered with the AI and their power ups (although, so far I've only played 2 player VS mode, I'm going to start Grand Prix today), but it's nice to know that you can turn them off. I couldn't find any customization settings really anywhere, except that edit license settings or whatever...
What I found annoying is that there is no coop Grand Prix mode. Me and my friends had a lot of fun going through and unlocking every character/kart/race together, but now you have to do it all through single player? Am I right, or am I just missing an option on the game... If it's there, I can't find 2 player Grand Prix mode. Does anyone know if you can do it?
Also, I read there was a mode in the game that's similar to Mission Mode on the DS (I think it's called Mission Mode, haven't really played the DS one that much), what is this mode called in Mario Kart Wii? Is it the Competition Mode or whatever?
I found that the Wii Remote actually did work well as a controller (a lot better than Excite Truck, but Wave Bird is still the best), did anyone else like it? Has anyone played it with the Wii Wheel too, I think it'd probably be even better with that?
