With a few improvements this game could have reached Sonic spinoff greatness. Improved graphics, removal of guns, vehicles and swears and you've got an excellent game. Really, apart from the homing attack it had the 3D Sonic gameplay down perfectly. Grinding was easier, jumping had a simlar feel to the older titles, and there was more to do then just run through the stages. Hell, they even squeezed in the co-op even though it was hard as hell to keep a teammate on screen.
