Not to mention that unlike the Dreamcast release, playing Crazy Taxi at the arcades allows one to enter their initials and score into the leaderboards. And if you're a real pro, you draw a little crowd. Nothing DDR sized, but a few people will stop and watch you get a class S license. Good thing about XBLA and PSN is that the community aspect of high scores come to the home console, though I doubt replays will be available.
