This game is pretty good for a sonic game (much better than shadow the hedgehog) but it's just to hard for a rented game, I never even beat the 2nt level. If your a sonic fanitic, (which is ok) pick this up, if this is the only game on your Q, pick this up, but if your like me and your Q is in a alwas full, skip.
i really enjoyed this sonic game. it went back to sonics ruites and we back to old school. a lot of the aspects of the game are very good. and with the DS you are paying more attention to both screens which is sometimes better. the special stages are also just as fun and also coming back to old school and using the format that the old "Sonic 2" game used. overall its a great game. maybe they couldve added some secret characters or a more character selection but over all its a great game
