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.
Resident Evil Outbreak. They've remade so many games and added so much PvP to the series, but Outbreak was an amazing and very fun co-op game that flopped because it used PlayStation 2 internet. I loved the game even offline and think it was way ahead of its time, and a rerelease with today's much more ubiquitous internet capabilities would be a hit, but they're obsessed with PvP game modes that I've seen very few people enjoy and most people hate. It would also give us more Raccoon City to explore, which I felt like they glossed over too much in the RE2 and 3 remakes.
