There definately is a lot of stuff driven via audiovisuals nowadays, but I think it's more a parallel to hollywood than it is to abuse gameplay.... big budgets, parent companies/investors not wanting to take risks, etc.
I reckon with a lot of todays games you'd be better off just buying the movie on DVD and sitting back and watching it with some popcorn instead of bothering to play the game.
If I wanted photo realistic graphics just to run around shooting everything, I'd be better of dressing up as Action Man and running around the woods at the back of my house with a paint gun shooting the squirrels, much more fun & plenty of healthy exercise too. Don't think the neighbours would notice as there used to my odd little ways by now...
