Sonic the Hedgehog may share its name with the Genesis original, but this game is even more broken than most of the other recent Sonic games have been.
The Good: The environments are at least colorful.
The Bad: Camera frequently gets in the way; full of little graphical and animation glitches; lengthy and frequent loading times always get in the way; town missions are just plain stupid; action stages aren't really much better. <_<
Basically about the same as Sonic Adventure, except now they're really harsh on the problems and on SA they let them slide.
No, it wasn't that the game was bad, it was how many lies SEGA made, if you dont know them then look on the What the He** Topic.
