Be it on PC or console, IMVHO games designed with care usually age quite well, just human characters' faces often age worse, but not if the graphics were cartoony, in that case, as long as the game was at higher than SVGA native res, it will age well overall.
An example of the former category is Thief series, environment aged very well, bodies decently, faces horribly. The games are still excellent to play.
Finally, once they reach a resolution high enough, and if dev team had artistic talent, 2D games simply are ageless.
