I'm impressed by how well they did the motion steering.
I think they did a great job on the controls also. And for those that would rather use a gamecube controller that's fine too. I think it's good to see both options available just like in Super Smash Brawl.
I tried out the VS races online and enjoyed the competition and ranking scale that is used. I need to play more single player so I can unlock some more content but I can't help but join an online race to thrash some random people around the states.
Griz what's your friend code for Mario Kart?
