I can't say that I am a big fan of racing games but from all that I heard I figured I would pick this one up. I was not disappointed at all. I own the first Gran Turismo for PSX and this game is a HUGE improvement. The graphics are amazing and the physics of the game are very realistic. There is a huge selection of vehicles (not enough BMWs) with tons of extras to add to your cars to boost them up. The sound is also great. While driving you have a bunch of songs to choose from that can set the mood for the race. The only downfall of this game is that hitting walls do nothing. I would like to see some car damage that you might have to pay to repair. This is something that bothered me since way back with the first Gran Turismo. But, this can be covered up with all the other great stuff there is in the game.
If you are looking for a game that will take you a long time to beat but still doesn't get boring this is it. There are enough tracks, events, and driver training to keep you busy for a very long time. I suggest that this game should be bought rather than simply rented because you won't get the full experience of getting bigger and faster cars unless you actually buy it and spend a lot of time getting them.
