In two words, this is just Forza Motorsport for Xbox with 'great graphics'
Tonight I was at the store, and I saw a father doubting what to buy for his 7 year son, and I recommended him PGR2, because is more arcade-like and suitable for those that do not have precise (or professional) driving skills.
The next important thing : you are going to need a wheel, believe me, trying to do minor adjustments in the driving line using the game pad is something that needs tweaking, because the car tends to veer to much at the slightest input. For those that expect a more forgiving game, this is not the one, remember, it's a racing sim, but still I found that steering the car with the game pad is less than ideal.
And probably as a result of this 'funny' gamepad steering and sensitivity, it's almost impossible to regain control of your car once you lose it, or trying to perform an aggressive maneuver. For example, if your car starts drifting, any professional driver knows that steering in the same way that your car's tail is going is a way to keep o regain control, whichever you need to do. In Forza Motorsport 2, once you are off the track, or your tail gets happy, be prepared for a visit to the rails, sand, grass etc. or for a ridiculous spin that defies any kind of real physics.
OK, this is a beautiful looking game, with hundreds of cars, but still limited on tracks. To be fair, this is the same old Forza Motorsport for Xbox with a new coat of paint.
Final word : I abandoned the first Forza because got too hard and the AI cheated so much, impending further progress in the game. I'm upgrading its score because is really a beautiful game, but to say that this is a next-gen racing game, is to give too much credit to it.
