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.
Fallout 1, in the style of Wasteland 2 & 3. With the animated talking characters similar to WL3. Include intended content for Fallout that was cut like some of the gangs, and side quests.
Rework certain skills like gambling to make it more integrated into the game; more effective at lower levels and less totally overpowered at high levels.
Revamp companions to make them more controllable. Selectable friendly fire. Ability to make companions wait in locations.
