Sonic always had good games on
Sega consoles. Even Sonic Adventure was good, showing Sonic can wok in 3D.
Games started getting bad when they started whoring out to appear in the special Olympics or whatever.
Sonic Adventure is probably my favorite Sonic game, period. The series can definitely work in 3D. The problem is that Sega itself has gone way downhill since switching to the game development only model that it now goes by. I know I'm always the first one
to say that the one thing I really, really want to see as far as gaming goes, is for Sega to return to the hardware market, but... I'm afraid they're too far gone.
