I believe this will mostly affects games which were lacking in technology.
I'd personally LOVE to see The Sims 1 or The Sims 2 re-released with performance and resolution upgrades, and, most importantly, made to be open world. Since they're older, I believe they could very easily render the entire map like The Sims 3, but with the charm of TS1 or TS2.
I cannot think of other games, since most games I see as adequate, whereas TS1 and TS2 were bound by system performance during their respective times.
Morrowind. Rpg that doesn't hold your hand through quest, well written plot and sidequests and a superb fantastic setting that is not all medieval Europe. Ashland, siltstriders, giant mushroom mage tower that can only be accessed by super jump or flying. And thosefucking annoying cliff 'bird thing.
Nerevar, you foolish one, approach. A character on the internet proclaims that our world must endure another cycle of annihilation and rebirth to find goodness. Can you fathom such grand and intoxicating innocence, Nerevar?
You there, sir! Be aware that I, Dagoth Ur, have witnessed 3743 years of existence, and I did not dedicate my millennia to be insulted by a creature not yet a century old. Depart from my lands and the ungrateful tribes, and let them remain untouched by your misguided notions.
I understand there is an open engine for morrowind with better graphics called OpenMW. Look for it here: https://osgameclones.com/
Probably my favorite RPG - Such a rich environment and a totally unnecessary amount of lore and background information in all of the included books and dialogue. Really set me up to be severely unfulfilled by everything else Bethesda made after that point.
Cliff racers will forever haunt my dreams.
I'd hope they'd rework/simplify the leveling attribute system though. I always end up modding that.
