I mean, if you’ve enjoyed Skyrim, honestly you can just google “best RPGs of all time” and play any that will show up. I’m gonna go against the grain here and say that Skyrim’s world is beautiful but nothing else is that great about it. Try enderall, fallout London, gothic 1+2 + archolos, mass effect 1-3, disco Elysium, Witcher 1-3, Baldur’s Gate 1-3, Neverwinter nights 1+2, dragon age origins, fallout new Vegas, pillars of eternity1+2, Kotor 1+2, south park stick of truth + fractured butthole, cyberpunk, fable the lost chapters, divinity original sin 1+2, etc.

If at any point you feel like the combat is too hard or whatever you can use cheats and just enjoy the story. All of these have pretty good ones. At least all of these have less grinding and better story than Pokemon games, in my experience.

Beyond that, just go for popular, widely acclaimed games such as rdr2, bioshock, whichever doom you want, portal 1+2, etc.
