I love this game! It's fun and it does have some flaws but it still deserves 5 stars. the story line was a little hard to follow but descently funny. turning is a little hard-but you can get the hang of it soon. the 'gear change' feature looked cool in the trailer but it's basically just pushing a button and changing boards. it costs rings: bad very bad. Some characters have to be unlocked by finishing story modes and missions. Like I said the story is ok but not great you can do the story as both sonic and jet but you have to finish sonic's point of view before you can do jet's. and there are 3 kinds of multiplayer so you can play with your friends as a team as enemies or play mini-games which are fun. i do wish though that in story mode you could pick who you are. and the game is auto-saving so you don't have to worry if you get through a tough level and don't save. it's a very good game I think it's better than mariokart it has a lot more features vehicles and characters.
