do they have a WRX in the demo, or a Corvette Z06, if so I can test how "real" it is...
I drive a WRX and my father owns a Z06, in PGR2 driving the WRX gave me goosebumps it was so true to the real deal in terms of acceleration braking and cornering, even the shift points. The sound was slightly off and it was PGR2 so it wasn't the best looking car but man the characteristics were DEAD NUTS.
There's no WRX in PGR3 but there is a Z06 and I got the same feeling from that as I did with the WRX in PGR2....
Even GT and Forza didn't give me that feeling when I played those games, they felt sluggish and less nimble. Now maybe they acted more true to life but felt different being fed through a controller and PGR was less true to life but attempted to make it feel real I don't know... all I know is driving the 'rex in PGR2 I knew what the car was going to do before it did it because it felt exactly like the car I drive daily.
