I'm very much enjoying this game.
We had a friend over to play with us the other night. He's pretty talented. What I like about the game in that regard is it doesn't fix what isn't broken, meaning that pretty much anyone who's played a variation of Mario Kart in the past can pick this one up and play it like he's been playing for years. It's not overly complicated, but it is absolutely fun as hell.
My friend was pretty much dominating us in the races. I could get a close second, but he was usually able to keep a good distance ahead of me.
There was one time though that counts as one of my favorite MK moments. On the revamped Cheap Cheap Beach stage I fell behind several places, with my friend in the lead. It was the last lap and I was pretty much screwed. Suddenly I picked up the three mushroom boosts. It certainly helped close the gap, but I was still behind a few spots. Then I picked up another three mushroom boosts. Got me right behind my friend. My last item pickup was a single mushroom boost. I waited until the final paraglide jump to use it. Passed him at the last second to win the race. Glorious.
