I would say that any game could be remastered beautifully if done well while properly honoring the original. Many games will be become unplayable for people as CPU/GPU architecture, display technology, and software development marches into the future. It’s important to have a way for the old games to remain playable with little-to-troubleshooting for the majority of players. Remastering games is a way to have that and make them look and play better as well.
On the extreme side of this, we have the “System Shock” remake by Night Dive Studios. That’s “REMAKE”, not “REMASTER”. This was was a staggering undertaking and a real passion project by the devs. The result is nothing short of a stunning, triumphant achievement that perfectly walks a fine line between what to change and what not to. They did a fantastic job, IMO.
