Early impressions with details have been pretty terrible. GameCube version of Sonic Adventure and no widescreen or any kind of online features, Crazy Taxi's music is different (heard some of the lyrics are like 'IM JUST A GIRL, WOOOOOAAAAOOOOH') and the stores like KFC are gone, no word on Crazy Box, either.
I guess at the worst, on the Xbox 360 version of Crazy Taxi you can put the real music in it, but KFC will be missed, and PlayStation 3 players are fucked.
