Crazy Taxi is a brilliant looking game. From the highly detailed and realistic roads and buildings to the nice looking cars. The graphics play a huge part in making the two cities featured in this game look and feel alive. There are also added effects like sparks flying out of your car which add to the graphics. The game also runs at a very impressive 60 FPS. In fact, it's very hard to tell any differences in terms of graphics to it's Naomi board Arcade brother. There is also occasional Slowdown, which happens to be unusual considering the fact that it happens when there isn't a high number of polygons flooding the screen. Both of these problems are far more frequent in the Dreamcast city. But they are only minor nuances and won't leave you feeling a little frustrated.
To say that there is a lot to come back for would be a lie. There is only ONE thing to come back for, and that is the fun. There is added Crazy Box mode which gives you missions to do and is a bit like a training mode, but you won't be coming back just for that. You'll be coming back for the incredible amount of fun that this game offers. The exclusive Dreamcast city that has been added to the home version of the game also highly ups the replay value.
All in all, Crazy Taxi is one of the most addictive games ever made.
