Repetition is the name of the game.
At least the game plays really, really well, and the power slide-to-turbo mechanics are very fun after you understand how to do it, unlike Mario Kart, you have to earn your boosts. It also feels a bit more... fair. Track design is also really good, so far my favorite is, probably, the icy one with multiple paths and seals running about. Items also don't feel as strong as in Mario Kart, which is a good thing if you value skill over chaos, but it still managed to pull me from last place to first place a couple of times.
As it stands, I just beat Komodo Joe, and while comparisons to Mario Kart are inevitable, the game does its own thing, just as the Crash Bandicoot games when it comes to platformers. I like this game.
