2d art and pixel art survive well because of the inherent abstraction being part of it’s aesthetician. The greater the graphical fidelity, the less the game leans on abstraction, and instead on fidelity, and then a remaster adds more visual appeal.

A game like slay the spire or katamari damacy gains very little from a visual remaster, but a game like Crysis would get a lot. Its worth noting that katamari damacy did get a remaster anyway…and its aesthetic is still what makes it look good, not the resolution. Crysis on the other hand had low aesthetic emphasis and heavy technical emphasis so refreshing the technical graphics does a lot for the game.
