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.
Some games need huge QoL updates. I’d like to see a balance of backwards compatibility along with the ability to toggle QoL settings. Give the player a choice to play OG or with modern QoL mechanics
