Man! What an incredible game! If every NFS was like Porsche Unleashed, than every NFS would be meant to be ranked 10/10!
This game is beautiful, the textures and scenarios and the cars are amazing! The gameplay is awesome and you really feel like you're driving a Porsche... actually, you feel like you're really driving a car (what won't happen in Hot Pursuit 2). And the sensation of being driving at 300km/h in a highway at a snowy sunset is just unbelievable! Much better if you own a steering wheel...
The difficulty is just right, which grows as you advance on the game.
And the customization of the cars is one of the highest points in the game. You chance engine parts, you change body parts, you change the rim, but the car still looks as it is meant to look, a Porsche!
Another great point is racing for winning a rare car! And when you lose, oh man! Check the price of the car and cry, because they are expensive!
Talking about money, I learned a lot about playing NFS while playing Porsche Unleashed... because before it, I was reckless, but after having to pay for every bump, every scratch in my car with my hard earned cash, I learned to use the brake pedal a little often hahahaha
To sum up, Porsche Unleashed is in my opinion one of the best NFS and racing games ever released, and even with great games as Most Wanted and Carbon, there'll still be some time to a better game to be released.
