"While many games on consoles claim to be simulations, most aren't. Forza 3 would have to be the closest thing to a real racing simulation than another game being released currently. I say that even knowing many Sony fans of the excellent Gran Turismo will be jumping up and down swearing profanities left-right and center.
The reason I say 'simulation' for Forza 3 is because it does simulate as many aspects of the cars in the games as humanly possible.
Not content to use 'canned' crash noises like many would, Turn 10 actually purchased vehicles and crashed them in order to obtain the 'correct' sound that would be heard when you do crash in Forza 3. Not only from outside, but from inside the vehicle, above it, etc, so that when you're in a 3rd person viewpoint, you'd hear a different noise from when you are on say the bonnet cam view."
