PGR 4 is a fun arcade racer, but lacks the polish of previous iterations. The menu system leaves something to be desired, the career mode is not very good, and the addition of motorcycles falls a bit flat. However, the fundamentals of PGR remain intact. It's still wickedly fun to drift. There are elements, such as the new garages and the implementation of the career mode, that seem half-hearted. While it's hard to imagine Bizarre Creations wouldn't put its full effort behind PGR 4, there's a definite lack of polish that was not an issue with previous iterations. Nonetheless, PGR 4 is one of the better arcade racers on 360. It just doesn't do enough new things right to push the series in a positive direction."
