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.
Knights of the Old Republic, Battle for Middle Earth
I played Battle for Middle Earth for so long! Personally, I liked first one better but I don't think the game would hold up to any strategy games standards nowadays. Once you know a few tactics you are practically undefeated in both of the games.
Kotor was the best game I've ever played but I got stuck in a puzzle on the floor in front of a wall . I tried playing it years later again but the loading times were horrible on the xbox.
I just played through it on mobile. It works well! Costs like 10 bucks.
Edit: you will need a Bluetooth controller for your phone though. I would classify the on-screen controls are terrible.
Crazy, I didn't know that existed. Same loading times as 20 years ago?
I don't know about 20 years ago but it loads pretty fast on my 200€ phone.
Speaking of Middle Earth, we need a new Shadow of game
Shadow of Mordor took me two attempts to get into it, but I'm glad I went back for the second attempt because the game ended up surprising me with how excellent the storytelling and gameplay was.
Shadow of War was pretty good as well, but the online stuff was starting to kill it for me and it was clearly designed with microtransactions in mind (even though I believe they removed them?). Still a fun game though, and didn't feel like a waste of money especially on sale.
A new entry in the series could be a lot of fun if they held true to what made Shadow of Mordor such a fun game, in my opinion.
