Reckon that kinda sums up why todays games don't impress me much, having started of with the VIC 20s 8 colours & the C64s 16 colours and being totally blown away at the time with what people could achieve with so little. It kinda makes todays stuff look like nothing more than a bunch of full colour screen grabs joined together as quickly as possible in order to lull folk in with that initial WOW factor and bugger the gameplay or heaven forbid actually making each game something new and different... 
While I agree to a degree that the more retro machines can be used in impressive ways, I'd have to say that the same has in recent times come true of modern games too. Once upon a time modern graphics power was used to hide a weak game, but proportionally I dont think there's a lot of difference between generic use/abuse of modern hardware vs. hardware put to good use for the gaming experience today as there was yesteryear.
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.
People arent easily impressed with modern titles these days, eye candy is a given whether the game is good or not, so it cant be hidden behind these days so easily.
Im a big retro game fan, the classic amiga is my favorite system, and I get a kick out of seeing what results can be obtained with aga and so I do get it, but sometimes I think it's easy to look back with rose tinted glasses. Although I agree gaming can be quite generic these days, it again isnt too far different from the amigas heyday, the main thing that's different is the genres. FPS's today, platformers or 2d shooters yesterday.
At the end of the day a well crafted game is a well crafted game and I'll accept all good applicants
