Hm....
You know, I never minded the music. It's pretty bad, now that I think about it, but I always blast my own on my stereo while I'm playing, so its never really an issue.
I agree with pretty much everything you said though, right down to the score at the bottom. Mine was 8.5, which is pretty much the same
Some of the things are odd with the game that you didnt mention, though. For one, there's 6 regions, and 4 teirs, but not all of the regions have 4 races. For instance, Fiji only has Bronze, Silver, and Gold. Kinda odd, now that I think about it. Also, the scarcness of powerups is weird....theres some levels with none, and then some levels with 2.
However, this is 2 on my list of Wii games, right above Wii sports. It's a great party game, and I found the learning curve to be practically nonexistant. The first time I played, I beat my brother, who had played for 3 hours. Then, my friend beat me on his first turn. It's a pretty even game.
I love the amount of cars and colors there are, too. Unfortunatly, some of the earlier cars become nonexistant when you get later, better ones...
Great game though. All, get it.
