The Octopath Traveler games

DayZ. Walking in the woods and hearing a deer in the distance or going up on a cliff and watching the sunset is quite serene.

Ghost of Tsushina

Minecraft? Or if that's too detailed, maybe Manifold Garden.

Uncharted 4 looks amazing, I was surprised to learn it's almost 10 years old. Feels like it could be brand new.

This might be weird, but Just Cause 3. When I was playing it a lot, I would just stop and look around at sunset and marvel at the view.

Okami and Child of Light are good options.

Death's Door

Season - A Letter to the Future

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.

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.

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.

• Death's Door just a stunning game in regards to art style and music/sound design. Really creative boss battles too that never felt stale. Can be challenging.
• Omno very chill game with a really cool vibe and music. No combat to speak of. Short though.
• Pseudoregalia PS1-style graphics but oddly gorgeous. It's a metroidvania of sorts with some of the best movement mechanics in recent memory. Highly recommend a look at least.
• A Short Hike really cute game that is all about exploration. As the title suggests, not a very long game. On the Switch version there was a toggle to turn off a graphics filter that is reminiscent of the 3DS. I personally liked it, but I have not checked the Steam version for the same option.
• Sea Of Stars releases on 29 Aug, but there is a demo available. Between the gorgeous 16bit inspired graphics, the lighting effects, and the incredible soundtrack this would be an instant buy for me if it weren't hitting Game Pass on day one! I may still plunk down on a physical copy. Leaning towards Switch, assuming it plays as well there as other platforms.

These are maybe not what some would consider beautiful, but I love the variation in art styles and how they can be beautiful while either being simplistic or retro-inspired. All but Sea Of Stars were very cheap during the Steam Summer sale or in a Fanatical bundle that may or may not still be available right now.

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.

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.

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.

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.

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

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

Not an entire game, but the freedom ending in The Stanley Parable is truly beautiful.

The witness can be beautiful at times, although the colours can be overwhelming at times

Rez

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.

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
