Growing up, I was never really a Sonic fan. One of my siblings had a Sega Genesis but we never used it much. The games were expensive and Super Mario World on the SNES was still so much fun. As I got older, I didn't play Sonic games much either. This is probably one of the first that I played and it isn't really a Sonic game.
This is Sega's answer to Mario Kart and honestly, Mario Kart is much better. The racing is solid but floaty at times. Switching between the different forms of vehicles is an interesting concept at first but can be jarring when moving from land or water to flight.
The cast of characters run the gambit of successful Sega franchises. Most of them I didn't know, seeing as how I never had Sega consoles growing up. Sure Sonic and his ever growing crew of friends are easily recognizable but some of them, I still don't know. I also don't understand why Wreck-it Ralph was in this. I guess they needed a tie-in somewhere but it just seems kind of odd.
This game isn't terrible. It has some interesting concepts and the racing is solid. But I still enjoy Mario Kart more. There is just something about it that makes it seem much better. It is so much simpler and yet there is still a lot there. The items are recognizable and the characters were ones I grew up with. Plus, this is the only game I have ever played on my Vita that has caused it to hard crash. A hard enough crash that the Vita asked me to send an error report to Sony. I have never had a Vita game do this and this is the only time I have ever seen it since.
