Crazy Taxi: Fare Wars review at Gamespot.

"Sad as it is to report, Crazy Taxi just isn't very much fun anymore. Though they were once shining examples of over-the-top, wacky-as-heck arcade driving games, the original and its sequels have not been treated kindly by the years, a fact highlighted by Crazy Taxi: Fare Wars for the PSP. This release includes Dreamcast ports of both Crazy Taxi and its follow-up, Crazy Taxi 2, then tosses in a bit of ad-hoc multiplayer, and calls it a day. What it doesn't do is adjust the game in any way, shape, or form for modern times. The shallowness of the gameplay is likely to turn off anyone who isn't intensely nostalgic for all things Crazy Taxi. And even those folk will likely take umbrage with the sluggish gameplay and dodgy controls in this version."
