I note that your post makes the assumption that the person you're responding to is an adult male. I know some people who would get very angry with you for making such an assumption.
Anyway, my point is that people have a tendency to exaggerate the negatives of their experience of a work while ignoring the positives. Would I rather GT6 had better sounds and better damage modelling, yes, but I'm not going to lose sleep over such matters. The only thing about GT6 which I can honestly say detracts from my enjoyment of it is the lack of endurance races, in which case I can just go back to one of the previous GTs, or play Race 07, or something. Otherwise, GT6 is a notable improvement on the 3 instalments which precede it, all of which were notable improvements on each other, and all of which were excellent games.
People need to chill out, rather than freak out about the fact that a very cool and relatively easy to implement feature might have somehow gotten in the way of Polyphony implementing better sounds in the game, despite the fact that the sound department probably isn't staffed by the same people who work on the skyboxes.
Chill out people, it'll do your blood pressure some good, and you'll ultimately be happier.
