The best game is Sonic Adventure 2. Anyway this game is really good. I try to get better times and every time I play it, I geta better time! Somethimes its hard to get a time, but with practice, you can get a great time! Speed Highway with Sonic for example. Its hard to get under 1:30 but you can find some shortcuts that saves you a lot of time and you need to go with nothing slowing you down. I got in Speed Highway with Sonic: 1:51:74 And I really got that time.
