The graphics could be better it looks a little blocky but it's not that noticeable. Other things that keep this game from a good score is that you can't pick where you want to drive, and not enough different courses. No two player mode which they could have made. There also could have been more places to take people and they could have made it in actual places which would have been cool.
Unless you really like driving people around don't buy this game at full price. The game will keep you busy for a while but after playing it for a couple of hours it gets boring. This game was more suitable for Dreamcast. Unless you see it in a bargain bin I can't recommend it.
