The one major improvement to the career mode in the PSP version is the lack of racing fees. Trying to keep up a decent cash flow in the previous versions of the game was a deeply frustrating process, as you'd constantly find yourself blowing cash on fees for races, as well as any damage your car might take during the course of a race. Those fees are gone, making it easier to keep your paper stack high and giving you more opportunities to buy new rides. Bear in mind, the mode still has its frustrating elements. For instance, if you decide you want to go and enter into a pink slip race at some point with a rival driver, you can't see what kind of car they're going to use until you've already agreed to race. Without backing out and losing some of your respect rating with that driver, there's no way to cancel out if you realize that they're racing a significantly higher-grade car than what you've got to work with, meaning that unless you're absolutely deft in your driving skills, you're probably going to lose. Most of the mode's frustrations are a collection of minor details like this.
