I think Sonic Adventure 2 Battle was the last good Sonic game I ever played, non-handheld anyway, I can't remember when Sonic Battle (?) came out.
Apparently Sonic Unleashed was awful. I don't know whether to laugh or sigh.
I miss the Sonic games in which you would press the right pad for 15 minutes and that would be the game. Surprisingly, those seem more fun than these new "SONIC DEFEETZ EBIL DURK FOARCEZ LOLO!" games.
