Surprisingly really fun. I hear a lot of people prefer this over Mario kart and I can see why. The transforming gimmick is really fun and the track design are really well designed and thought out and used the transforming gimmick to it's advantage. The missions are also pretty fun but this is a big gripe I have with it. So I first decide to beat all of them on hard to get it over with. But after I didn't them all on hard it unlocked the expert difficulty on all of them!! So I had to replay all of the missions on expert! And there's like over 100 of them!! I dropped the game after that because that's just a time waster and you don't even get anything from it so I will not be 100% it anytime soon. But if you or a friend are tired of Mario kart give this one a go you won't regret it.
