Gotta be more specific. What about Skyrim are you seeking elsewhere?

The VR version with a ton of mods lol

There are a lot of good recommendations in here, but if you like Skyrim that much have you considered playing a total conversion of it? Enderal: The Shards of Order Is so different that is basically a completely new game, but within the concept of Skyrim, it’s engine, and a lot of its assets. Think the change from ocarina of time to majora’s mask, but even more extreme

Red Dead Redemption 2

Witcher 3

Kingdom Come Deliverance

Kingdom Come Deliverance 2. Not the same kind of "magic" but if you want immersion and a super rewarding story I highly recommend it

Have you tried Skyrim: Anniversary Edition, Skyrim: Special Edition or Skyrim: Legendary edition? /j

Man I haven't played Skyrim since the Xbox 360 days on my CRT. Other Bethesda games I played recently were Fallout 4 and Starfield.

FO4 was disappointing and Starfield was fine but I never finished it

For me it was Witcher 3 and the dlc. Love that game so much..

Ok you want something as rich and interesting as skyrim, so I'm assuming open world games are your jam.

There are three games you should play.

1. Red Dead Redemption 2 - it's a Western, the world is very believable, and it makes you feel like you're really part of it. You can follow the main story line, or you could spend your days hunting and fishing. You could travel from town to town playing every poker game you can find. You can conduct train robberies, breed horses, really, there's just a whole lot to do.

2. Cyberpunk 2077 - this is RDR2 but in a scifi dystopian future where the corpos own everything, sex is for sale on every billboard and every ad break, and the only justice is what you can achieve on your own. You've got a ticking time bomb in your brain and no time to fuck around. In this world where you can't trust anyone, somehow what really matters are the friends you make along the way. (seriously)

3. The Witcher 3 - from the same studio that made cyberpunk, the Witcher 3 is truly a masterpiece of storytelling. The one caveat I have for this game is that it starts hard, almost "souls-like". But get past that first rough hour and there is an extremely rich world with a seemingly unending collection of stories to become a part of. This may be the most skyrim-like of the games listed here, but you're in for a treat, because this is a much better game than Skyrim.

All three of these games are gonna make you feel real feelings, they're all actually better at telling stories than Skyrim is. The Witcher 3 in particular loves to live in the grey zone, it'll make you make ethical choices that matter, and you probably won't like any of the possible outcomes. But this is a good thing!

Tainted Grail: The Fall of Avalon is on sale on Steam right now. I've only played through the prologue, but it seems pretty good so far.

Oblivion.

Heavily depends on what makes Skyrim special for you.

The most obvious similar games are other Bethesda titles, especially Oblivion and Morrowind. Install some QoL and graphical mods, and you should now have 3 Skyrims.

Telling people what in particular you like about Skyrim is going to get you much better feedback as there are many, many games that are similar in some ways but not others.

I still haven't played through Skyrim.

Witcher 3. That castle ruin over there? Might have some loot. Or a Cockatrice. Or a psychological horror story of 10 parts. Or nothing at all, who knows. And you might stumble over Excalibur by that lake.

Also get the "Blood and Wine" DLC, absolutely worth it, even if you're not into the story. And the HD Reworked mod if you like it more realistic and dark, one of the best reworks ever.

Edit: there's now Next Gen too, huh.

OpenMW

If you want the same world building and hadn't given it a try, Elder Scrolls Online is still great, can be acquired for cheap (even the base game has a lot of content), and be played almost fully solo!

If you didn't mind the "floatiness" of Skyrim Combat, ESO is great, has a lot of world building and exploration, can be quite immersive at times, and basically has the look of a modded Oblivion.

I spent a good 400h on it, mostly on lore discovery, main and side quests, and farming not for equipment but to get furniture for my house! (and if I recall I still didn't reach the max level, not a pro-player).

I never played it as an MMORPG, but more as a coop RPG while still playing solo most of the time. So I can't judge on the quality of the MMO aspects (though the cyrodil constant battle system is quite fun and intense).

Rdr2 my friend, rdr2

I can give you older and with worse tech - Morrowind is better than Skyrim

Enderal. Which is... a skyrim mod. Although calling it a mod does it a disservice, it's a whole new game.

Kingdom Come Deliverance 1 was great.

But it's a Medieval RPG, not fantasy. So you won't find elves or orcs or magic.

Edit: Actually nevermind, don't play it, it's too strict of an RPG, not for everyone, (i.e. fighting more than 2 people can kill you easily unless you master the combat, using a bow won't give you the center reticle, saving the game needs a specific item or you need to sleep in a bed, wearing a helmet will limit your vision to the shape of the visor, etc)

I suggested this because my Skyrim was modded to be a strict RPG as well.

This might just be too obvious, but nobody's mentioned it... Have you played the other Elder Scrolls, like the Oblivion remaster?

RDR2 and Cyberpunk. Although they are more linear roleplaying games than Skyrim's experimentation.

You need a lower dopamine threshold to make the most of those games, but they're a treat when you learn how to do that.

Might sound weird but maybe STALKER. They're both older, very charming but very janky open world RPGs, and both have immense modding scenes that have created an experience greater than the sum of its parts.
