PGR3 is one of the best racing games I have ever played, simply amazing.
Story - Become the best racer in the game. By doing this you need to become the number 1 ranked racer in the game.
Graphics - Wow. When I first played this game, and the race was about to start 5...4...3...2...1, I was looking at the car from all the different angles and thought holy **** look at that, but then, the race actually started, and I realized those are IN GAME graphics, I was simply blown away. However they do have some noticable jaggies and pop up in the beginning of the races, but this game is simply beautiful.
Gameplay - This game is a mix between sim racing and arcade racing. It has sim physics where you can't just book it into a turn and expect to completely drift around the turn without hitting the wall, but it also has some arcade elements mixed in where it is more forgiving than a sim so that you can actually drift around corners with practice and precision. It would have been nice to see some rain or weather effects to see how the cars would react to a slick road, but all in all the gameplay is top notch.
Sound - The sound in the game is great, the engines in the cars all sound noticabley different, the roar of some of them sounds very nice with a nice sub woofer. The sound of the cars whizzing by is very nice too. The music in the game is very different, it has some known music, but it also has some unique songs too, it also has classical music which is one of my favorite genres to race to. If you dont like the music there is always the option to play your own music which is nice.
Length - The game has 4 difficulty setting where hard and hardcore, are, well, extremely hard, they seem impossible but, like they say, practice makes perfect. There are many tracks to race through, but there could have been a few more, it will take you maybe 4 hours to get through all the races in each difficulty setting. However, in order to completely beat the gae you need to be ranked number 1, which will take some time.
Replay Value - As stated above, there are 4 difficulty settings making this game very easy to come back to since the last 2 settings are very difficult. There is also 8 players on xboxlive which makes for endless gaming since there is always a race going on.
Overall - This is my most played xbox360 game out of the 5 that I own, it is one of the most fun and I always come back to it. It is a fabulous racer that should not be missed. Do yourself a favor and add this game to your xbox360 library, you will be glad you did!
