+ I love the textures on the Super NES tracks. To quote myself, it's like a 16-bit dream.
+ Some sweet new tracks. Koopa Cape is awesome.
+ I was worried, but I approve of Yoshi's new voice clips.
+ Use of Miis very light, tolerable. I won't be playing as one very often (still haven't unlocked that feature yet, but I want to play Mario Kart... as Yoshi).
+ Though snaking is said to be taken out, you can still kind of do it... drifting back and forth on straightaways is still possible, but it takes a little longer for the boost to happen, so it's a bit slower.
- No WarioWare Wario (c'mon, at least just for bikes?)
- No individualized karts or bikes. I miss the Egg 1.
- Not the best retro choices. Mario Circuit 3 rocks, but bad DS and GameCube tracks. Waluigi Pinball is the only cool thing with Waluigi's name on it, and I LOVE Wario Collosseum.
- Too many Piantas. What do they see in Mario Sunshine?
