Skyrim and the mainline Elder Scrolls games (Oblivion, Morrowind) can run fine on most setups these days. Skyrim: Special Edition was released in 2016, which is almost a decade ago now.

Problem with them is sometimes mods are required for performance because they can be optimised terribly. There are actually some good mods which make the games play a lot better on older hardware, actually, but it’s been a while and I don’t remember them.

Still, you’re going to want to play mostly un-modded because too many mods will tank an older system. I personally think vanilla Skyrim can be pretty fun, so it’s not a big deal, IMO.

The combat is a huge con, though. Bethesda hasn’t ever really been “good” at melee combat, and have only started to improve their gunplay starting with Fallout 4.

That said, since I’ve brought up FO4, Fallout 3 and New Vegas should run fine pretty much anything. Although, when I say “fine”, I mainly mean “work”, because optimisation is still terrible and bugfix patches might be needed.
