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.

If you don’t mind missing features, there is mineclone 2 for minetest, written using lua. There’s also a mineclone 5, but I’m not sure if it’s actively maintained or developed as of now and is most likely behind 2.
