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.
One thing DA 2 did really well (though a deviation from the crpg formula) was making it feel like your companions had lives of their own. When doing their quests it felt like you were joining them on their own adventure, as opposed to just waiting in camp to follow you.
