Ghost of Tsushina

Both Sludge Life games. A bit unconventional but I found a lot of spots in the games where I would just stand there and take in the various scenes going on. Both games can be beaten fairly quick but it took me hours to get through them because I kept stopping to just take in everything going on.

Firelord is an old one but gorgeous. Chicory is pretty, in a colouring book sort of way. Child of Light and Forgotton Anne have fairly similar aesthetics but are both lovely.

INFRA! Just look at the screenshots on the Steam page.

Death's Door

Season - A Letter to the Future

Endless Legend is the most beautiful 4x game I've seen so far. All of the races are great designs and feel really different in gameplay.

Video game

Horizon has some beautiful moments

Back in the day, I thought Oblivion and Skyrim had some beautiful spots although it may not be as impactful now as it was upon release.

Board Game

Sagrada is a game where you are building stained glass windows and I think it's pretty.

Monument Valley. Visually beautiful enough to warrant repeated play-through just to admire the design, and conceptually brilliant as well.

And another vote for Gris, too.

The Vanishing of Ethan Carter, but yeah, it's basically a tech demo/walking sim

I can't believe no one has mentioned A plague tale - Requiem! It's a stunning game to just soak in the atmosphere of middle age France.

The Witness

Blasphemous. Part 2 just released, btw

I really like the hunter call of the wild. it's not perfect visually, but there have been moments when i just stop to look around and not even care about hunting

I find peace and beauty in the wilderness of DayZ

For more immersion, you might wanna try VR. And if looks is what you're after then PCVR for specific, although there are some impressive contents on mobile VR too.

Both Subnautica games and Tunic.

Rez

Elden Ring looks beautiful. You just need to get used to fighting a boss 100+ times before killing him ;_;

Horizon series is good. The 2nd game, Forbidden West is so good I used to open the photo mode at random spots and take pictures because I found the scenery beautiful. I would definitely recommend it.

Ghost of Tsushima is also beautiful. However I got bored pretty quickly but others have enjoyed the game so maybe you'll like it.

Also Skyrim with mods (like ENB) can be beautiful as well :p

A game I'm not seeing mentioned here but for me it's one of the top games is Ark. I have so many... Ok, it seems I HAD so many glamour shots of the world as I played it. HD death has lost me a bunch of largely meaningless micro-memories. Well, I still have the memories, but it makes it harder to share them. Here have this one:

Arise: A Simple Story

Sons Of The Forest is surprisingly detailed, but you don't have much time to take in the sights and the foliage when there's cannibals chasing you through the woods.

Cuphead is absolutely gorgeous, it's just hard to appreciate because you're constantly trying not to die.

I grew up with Felix the Cat and Popeye and Betty Boop on VHS, not because I'm super old but because we were poor farmers. Cuphead is the only game I've ever played that has recreated this ancient animation style and it is done so incredibly well. It's a masterclass in art style and gameplay at the same time.

Many of those already mentioned are great looking. I would add a personal choice, aesthetically pleasing for my taste: Dyson Sphere Program.
