Sega seemed to try and re-invent the wheel on Sonic games and they pulled it off quite nicely
GRAPHICS 6/10
-These visuals aren't anything that can steal your breath but they are tolerable and they won't hamper your enjoyment of the game. The cg cutscenes seem a little off even for its time. But whatever lets move on. Also for in game cutscenes; they are really poorly done, even for the time it just looks really weird
SOUND 8/10
-The voice acting was very rough in this game. The actors seemed like they were trying way too hard and it was kinda awkward to watch. But the music in this game was awesome. There are so many great tracks it's not even funny. I guarantee you will love it.
STORY 10/10
-To be honest, I don't really play this for the gameplay. I play it for the fricken awesome story. Its not so much the plot that got to me. Its more of the characters. With the exception of Amy, not a single character was neglected in this game. I loved every single one of them.
SPEED ELEMENT 8/10
-Sonic can get moving pretty damn fast in this game. Not so much to say though.
GAMEPLAY 8/10
-Where do I start? They focused on every single character's gameplay. The treasure hunting levels are kinda boring but it was a nice attempt for variety. Playing as Eggman in story mode? Come on, how could you say no to that. The variety of upgrades for each character are also pretty cool to find. I don't have to much to say because you just need to play the game and you already see its awesomeness. Fantastic job sega.
