Playable from the show floor at E3, Xbox Live Arcade and PSN ports of Dreamcast classics Sonic Adventure and Crazy Taxi have some quirks.
All of the licensing from Crazy Taxi is gone, including the trademark music and various Pizza Hut references. Generic stores and music now replace them, the unfortunate part of modern day re-releases.
Sonic Adventure, while not technically losing anything, will be in 4×3 with no option for widescreen play, unlike its co-release brother. Sega claims the game could not be coded for 16×9 play.
