I think old-fashioned 3D graphics get a really bad rep, while old-fashioned 2D graphics totally get a free pass.
For some reason, "pixel art" is hip and chic and Liz Lemon glasses wearing college students crank out blocky, 2D "art games" and nobody seems to mind. People build Mario pixel-by-pixel out of post it notes and submit the pics to Reddit. The list goes on. Oldschool 2D is in.
But when it comes to oldschool 3D graphics, there's no love or nostalgia for it. (Except maybe retro arcade vector Tempest-style graphics.)
I think that's kind of strange, because yeah, I can look at Outcast or Turok 64 and say, "No horizon, muddy graphics, blah blah blah," but then I'd also have to trash NES graphics or Gold Box games because they're technologically inferior to the 2D beauty of a hand drawn Sega Saturn title or pre-rendered beauty of Baldur's Gate 2. (Nobody seems to have an issue with the art design as much as the low polygon count, or blocky voxels, or some other technical aspect.)
It's weird that when a game with old-fashioned, low-tech 2D graphics comes along, people eat it up. But when a game with old-fashioned, low-tech 3D graphics comes out, people go, 'Hurr hurr, Crysis looks better!'
