Conceptually, the game doesn't seem that complex. Choosing to race as either Sonic, Amy, Aiai or Amigo (many more characters are promised but Sega's reps were sworn to secrecy), you hop in an over-the-top, character-inspired vehicle and race across various Sonic-inspired lands. Now let's think about that for a moment: racing and Sonic-inspired lands. Sonic has always been about speed. On the Genesis, his level designs were amazing. What might happen if you were to take those elements and bring them to a 3D racing game? You'd get Sonic and Sega All-Stars Racing.
