it is ok....
Gameplay: Beautiful. You have this huge playground and you go on to the levels and beat the boses. You can also choose from 4 different players that you can play in each level.
Graphics: Beautiful. One of the best graphics on the gameboy advance. Sonic and his crew are stunning and the bosses are beautiful.
Sound: The sound isn't diffrent then the last title so there isn't much of a change between does in two in the sound section.
Value: You can play for hours and hours trying to finish the game with all the chapters. But still I wish for an online feature.
Reviewer's tilt: Overall this game is an awsome game for the gameboy advance and you should definitely buy this game.
I didnt like it all that much though because It is hardest to control sonic because be is so fast and when you plsy as him you cant make up for your actions like you can with knuckles, cream, and tails, it would have been better if all the sonic charchters were on here though.
