I just brough this games and beat it in less than 24 hours, but to be fair I played non stop untill I beated the last boss and I havent gotten everything unlocked, but I will eventually. This game has alot of short movies in it and the game play is amazing too. I played it for the wii, but im pretty sure is going to be the same for the other platforms, I personally like the intro movie its pretty amazing and I liked playing as regular sonic but its just my opinion, so go buy it and enjoy.
