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... 
Wasn't it max 4 colours on screen on VIC-20 from a palette of 16 (only 8 for inside the border though) Anirog Skramble for VIC20 looks pretty good compared to the C64 version except the resolution on VIC is pants.
Anyway each step has produced a marked increase in quality.
VCS/Intellivision/ZX81 to
C64/Atari 5200/Amstrad etc
Amiga/SNES/Genesis/VGA DOS
Software 3D on DOS PC/PS1/Saturn/N64
PS2/Xbox/Dreamcast/Gamecube t
PS3/360/£300 GPU + i7 in PC etc
Ok the last generation is the start of refinement/photo-realism sure but it is still very noticeable to me. Popup in games affects gameplay despite being a technical issue too.
You couldn't do something like Jet Set Radio Future before Xbox level of graphics and what an awesome and original game that was, a true class act. Ditto Shadow of the Beast on anything other than Amiga was a waste of time too. Every evolution will have games worth playing end of story.
But I do believe this is the last generation where any improvements in graphics are going to be barely noticeable and we only have 2 ears so 5.1 sound is enough
