Horizon Zero Dawn is on steam. Amazing game. Open world. I haven't played the second one yet but I need to.

There was one called Immortals Fenyx Rising that I remember being quite similar to BotW. Unfortunately it's Ubisoft

The Outer Wilds

All due respect to the other recommendations in this thread (The Witcher 3 is in my top 3 favorite games ever), but I get the sense you're looking for a similar vibe - that self-paced, quiet, almost lonely exploration where, though you do have a goal, the point of the game is to wander the world and discover things. While most of these recs (and most open world games in general, so it's understandable) have a strong story focus, The Outer Wilds will give you that quiet, unguided exploration BoTW does so well.

(And I know explicitly turned down souls-likes, but Elden Ring also hits that vibe super well. If you're really stuck for something to play, it might be worth a try with one of the magic-focused builds that significantly reduce the skill needed)

I would imagine horizon zero dawn and the Witcher would be what you're looking for.

I've found Palworld to be a lot like that, and it's hitting 1.0 in July or so.

I kind of cringe at suggesting this, but Genshin Impact is if Breath of the Wild used a gatcha payment model instead of $60 up front.

Here is a few I can think of that are a bit similar

• Sable
• Bastion
• Planet of Lana
• A Short Hike
• Spirit of the North
• TASOMACHI: Behind the Twilight
• AER Memories of Old
• The Witcher 3: Wild Hunt

Btw, you should definitely try Elden ring if you haven't already

Have you tried Legend of Zelda: Breath of the Wild for PC? They even have it for Steamdeck. I love my Nintendo Steamdeck. I even got a Nintendo Steamdeck 2.

Immortals: Fenyx Rising

Sable

It's like Breath of the Wild without combat.

Crimson desert. You'll never finish it.

Crimson Desert is very inspired by BOTW/TOTK, and a bunch of other games, rolled into one. It's also on PC*.

*it uses Denuvo tho.

Skyrim

Admittedly it's a bit older

Horizon zero dawn is live action breath of the wild

Enshrouded

Morrowind, Fallout, and Dragon Age are all quality contenders.

The oft forgotten ~~Gods and Monsters~~ Immortals Fenyx Rising is a shockingly good BOTW-like. Booted it up the other day because I noticed I had it from when they gave it away for free some time ago, and it was such a pleasant surprise. In some ways (combat, traversal, dungeon design, writing) it’s even better than Zelda. Do yourself a favor though and remove most of the HUD and puzzle hints via the ingame options and pirate it if you can so you don’t have to deal with Ubisoft Connect and Denuvo.

TUNIC! Play Tunic!

Palworld full release is coming next month

V Rising. It's basically goth Terraria. You're playing as a vampire who just came out of a thousand-year hibernation, and your whole goal is to find and kill Dracula. You start by bullying skeletons with your bare hands to harvest their bones, and go all the way to building an enormous automated castle that can process thousands of units of raw materials.

Honestly. Try Dragon Age Inquisition. It isn't "open world", but it has MASSIVE regions (that people complained were too big). Lot's to explore, plenty of side quests and puzzles. A base you can customize. Armor too.

Edit: Honestly, play on easy if the combat is too annoying.

Sounds like Crimson Desert
