If that were the case, we would only really love the games we grew up with. I stayed at an air bnb that had a ps2. I sat down and played ace air combat; a game I'd never touched on a console I'd never had as a child, and I had a blast.
I also recently picked up fallout 1/2 for a couple bucks on steam, and while the controls and graphics weren't great, I still enjoyed the game even though I never touched it in childhood.
Realistically, there are a few games for the xbox / ps2 era where the graphics really have not aged well, but for the most part I am not a pixel snob, at all.
