Summary: Out of my collection of about 30 games, this is clearly the best in every way, and whenever I get tired of playing another game, I know I can come back and play Gran Turismo. There are over 800 cars in the game and I don't even know how many courses. I can purchase almost all my favorite cars and race them on onroad or offroad courses. They have a good range of cars too. Cheap cars, expensive cars, old cars, new cars, powerful, not-powerful, you get the idea.
Summary: Finally Gran Turismo makes it to the PSP after an aborted release a few years ago. Anyone who trained on GT4 will adapt quickly as many of the same tracks are available here. Differences are the "single race" mode is similar to the old "arcade" and the "driving challenges" so far are mainly short tests, but there are 50+ tests. Somewhat easier than GT4 you don't have to get gold in order to pass a challenge, bronze will do.
Summary: I recently bought an old PSP for £20 just to give it a try. This game is one of the reasons why- I absolutely love it! It fills the gap when I can't be at home on Gran Turismo. It reminds me most of a blend between GT3 & GT4, a lot of the more complex stuff is missing from this PSP version, but for me it has what I need on a handheld console game. Good fun being able to blast round Nurburgring wherever you might be with your PSP!
Summary: Its a poor version of the playstation series, there is nothing to really work for, you just race in whatever car you want, on whatever track you want, and then you earn money to buy another car.
