There is no career mode in this game. It lacks structure. The only incentive to keep playing is to win one race at a time so that you can earn money to purchase more cars. There are limited tuning options, but car parts cannot be upgraded.

The graphics are good. However, I think all the tracks originated in other versions of Gran Turismo. Also, there are only four cars on the track during the race.

There is no internet multiplayer. If you want to play against another human being, you will need to have friends with PSPs.

In short, this game is not worth full price. If your a fan, you've waited four years for this game. Save some money and wait a little longer.

I have to say I'm disappointed with Gran Turismo for PSP. After waiting for years, you'd think Sony would have built a masterpiece, but this is surprisingly not fun. Ridge Racer by Namco is by far better than this game.

Game Interface:
The interface is very confusing and it took me awhile to figured out what was going on. There's no way for anyone to jump in and play a game without going thru tedious setup and selection. This flies in contrast to other racing games where you can jump in and play immediately.

Vehicle Selection:
This is very bad. Only one car to start with?? Why?? Not only that, when you have enough credits to buy more vehicles, you are only given a small subset of brands to buy from. And the subset changes each time you completed an activity. Once again, why??!!

Race Tracks:
Now this is the positive part about the game. It has a good selections of real world race tracks. No complain here :-)

Game Play:
Still playing with the game. No real complain yet.

Overall, the user interface and vehicle selection really put a damper on the gaming experience. I really want to jump in and play a quick game with my favorite vehicles. This game does not allow for that.

Sony could have made this a great game, instead, it's less than mediocre...

I got this game knowing what it was, a fun psp sim. racing game. I know theres no career mode and no buying parts but its still a good game if you know how to play it. By that i mean get as many cars as fast as you can and here's how. Go to the test track, it starts at 50,000 for the first race then when you get to level S you get 150,000 for 1st. I was up to 1,500,000 in no time and getting all the cool cars i wanted, and if you check the dealership every 20 to 30mins there are always new brands.

So if you want to get a lot of cars do that then race all the tracks later its much more fun with 20 cars that are all top noch.

This game's graphics is as good as a PSP game can get. The races are stunning and there are lots of cars to choose from. Every 2 days there are 4 different dealers you can buy from and you can race alot and save up to get lambos or make do w/ cheaper GTRs. However, there is no story or mission mode, so this game tends to become boring after awhile. If your looking for racers that has a story than this is not yourr game, but if your interested in collecting cars or just want to race than there is no better racer than this for the PSP.

I recently bought this game at Gamestop, and to be honest, I was a little too exited.

I popped the game in and browsed the cars, I wasn't happy about how the car buying was made. Basically it goes like this, when you first start the game you're on day 1, and then whenever you do a race or a license test, it goes to the next day (e.g. day 2, day 3, day 4, etc). Every one or two days, it gives you another 4 dealers to choose from. I hoped that they could just show them all at once because it took me 12 races to finally have Toyota as one of the dealers so that I could buy the Prius. Even though this limits the convenience of getting a certain car, the car selection is amazing (800 cars). First off, there are some car brands that I never even heard of, and I know alot about cars. In the car collection, there are many antique cars, like my 63' Alfa Romeo. Old cars are good and so are the newer cars, some of the cars are even concept cars (prototypes).

The car collection is great, and an added bonus is that the cars are beautiful. The only car I could compare with a real-life counterpart is the Toyota Prius, and it looks the exact same, they even have the little "hybrid" tag on the back. The paint selection is also very good and the selection for each car is based on the selection in real life, which was great because I found the exact color of my mom's Prius (i'm 13). Also, the statistics (e.g. height, weight) are completely accurate which lets this game double as a car encyclopedia.

My opinion about car customization was mixed. You can have 30 cars in your favourites, and you can tune those cars to you're exact specifications (e.g., you can modify the engine's power, the damper, the spring rate etc), you can even modify the transmittion (manual or automatic), and you can even modify the type of tire (even though there are no specified brands).

The racing is great, and unlike Gran Turismo 5 Prologue, the cars fight back if you bump them, and try to cut you off if you try to pass them. There are also 35 beatiful tracks to race in, ranging from a nice track in the city, to off-roading in a forest, and even gliding on the snow in a winter course (remember to put on you're snow tires!). There is also license testing which is very similar to that of Gran Turismo 4, but in my opinion, better.

The ad hoc mode was very well done. Recently, one of my friends got Gran Turismo for his PSP Go - Black and we tried the ad hoc mode. First we tried a race, it was very fun, you can use any car from your garage and then you vote for a track. I especially liked that I could let him have a head start because I am much better than him:). Trading cars is great, for most of the cheaper cars, you can simply give them one and you will still have one in your garage. For more expensive cars, you can trade them. Having a Gran Turismo buddy is a huge advantage.

One huge feature about this game is synchronisation with Gran Turismo 5. Kazunori Yamauchi recently confirmed many features of Gran Turismo 5, one of them being the ability to synchronise your car collection from Gran Turismo with it, giving you a head start for when it comes out.

In conclusion, Gran Turismo is great for collecting cars, but not to good if you want a virtual career as a race driver.
