A lot of early 3D games have aged relatively gracefully, and a lot of late 7th generation games age pretty well too. But between those two periods is a period whose games have NOT aged well. Most 6th generation games have aged horribly. I feel like it's somewhat similar to the uncanny valley somehow. There's enough details for those games to look better than earlier games, but as soon as you increase resolution, you notice how something's wrong.
2D games age better. I think almost all 2D games with proper sprites have aged at least tolerably.
You can probably tell I don't mind low-level graphics very much...
