The last good Sega game I played was F-Zero.
Everything after that, with the possible exception of SMB2, was total, utter crap.
I have ZERO faith in Sega to create anything worthwhile. As a child, I worshiped Sonic like a god but now that Sega has seen it fit to whore him out to every goddamn console ever dreamt (even the ill-fated N-gage), he's basically dead to me. I bet there was a Sonic game in the planning stages for the Phantom.
Seriously, f*ck Sega. They have all the business know-how of a drunken hobo and I can't understand why Sammy would effectively buy a sinking ship.
