What the sound of motors me is most excited about the sound really mega good. This is in addition to the good range of many car makes the most important for me because it interested me not what music is played during the race, the engine sound is the music !!! This is still perhaps is the driving physics did a good job not as good as in GT5 but this is in my opinion a matter of taste. The graphics are not up to date on my mind but you can not get out get out so an outdated console even more graphic beauty nunmal. But still enough of this completely for the current 1080p screens.
I have long GT5 gezoggt but Forza 4 has won the comparison alone the sound can already be better in my opinion. Well I love the sound of the engines just about anything from 6-12 cylinders "Oh glorious" Good home theater system provided!
The only thing I was a bit's criticisms is the high price for the Car Dlc's. But one must not buy any DLC.
So for all the worth are particularly good sound, a solid physics and on a comprehensive selection of vehicles, the purchase in any case.
