Project Gotham Racing 3 offers players four cities—Las Vegas, London, New York City, and Tokyo—as well as the Nürburgring to race through. Project Gotham Racing 3 features 80 licensed cars from over 30 manufacturers such as Ferrari, Dodge, and Lamborghini. The polygons used to make up a car model increases in Project Gotham Racing 3, to between 80-100,000. The increased polygon count allows for smoother, less jagged-shaped cars than in earlier games. Of the 80 cars in the game, 71 are unlocked and available for play at the start of a new game, while the remaining 9 cars are left for the player to unlock. In a change from the previous two games, Project Gotham Racing 3 emphasizes supercars and special models instead of generic production cars. One of the starter cars is the Acura NSX. Similar to its predecessors, each car in Project Gotham Racing 3 is allocated to a specific class. There are five classes, A through E, the high performance cars being Class A, and the low performance cars in Class E. Kudos once again play an important part in Project Gotham. Kudos points are given for stylish driving, for example drifting around a corner, drafting, or getting two or four wheels off the ground. When combos are linked up, the player is given a bonus for keeping them linked together, and this builds up to huge amounts if the combo is held for a substantial length of time. This bonus is, however, lost if the player crashes into any barriers, though the base Kudos are kept.

Reception
Project Gotham Racing 3 received "generally favourable" reviews according to video game review aggregator Metacritic. USA Today gave it a score of nine-and-a-half stars out of ten and said it "offers plenty of "oohs" and "aahs" with impressive graphics and sound. But luckily this game still plays very well too. And with a robust online package and plenty of racing options, it becomes a 360 must-have." The Sydney Morning Herald gave it four stars out of five and said that "Despite Gotham's obliging nature, high-speed thrills and gorgeous graphical sheen, it's hard not to feel that we have seen its best tricks before." However, Detroit Free Press gave it a score of three stars out of four and stated that "Online play is as hectic, though perhaps not as friendly, as the previous Xbox version." Project Gotham Racing 3 received a "Platinum" sales award from the Entertainment and Leisure Software Publishers Association, indicating sales of at least 300,000 copies in the United Kingdom.
