Really encapsulates the meaning of beauty a couple different ways.
Tetris Effect, particularly if you can play in VR.
Though if you're strictly talking "aesthetically pleasing", the options get wider. I absolutely loved the aesthetics of Hi-fi Rush. The absolute beauty of this comic-esque, cel-shaded world with every element, background and forground, moving to the rhythm of the soundtrack just blew me away when I started playing. But I'm a slut for rhythm games, so there's just something about everything tiny fiber of the space connecting and syncing up that gets me.
I think if you enjoyed the beauty in Hyper Light Drifter, then you will be entranced by Tunic. Bonus points for being one of the best puzzle exploration games of all time.
Spiritfarer is very, very pretty as well. It is dripping it atmosphere and I often found myself just afk breathing it all in.
Witcher 3. The scenery there is just beautiful. And you get your first beautiful scenery pretty much immediately in the tutorial, just go to the balcony in your room and look.
Guild wars 2 has one of the best artstyles of any game IMO. Also very nice to just explore the world and the core game is free 2 play with a generous way to buy and keep forever without sub or mtx.
Outer Wilds has a lot of beautiful things to look at, whether it's a planet or moon soaring overhead impossibly close, or something more cosmically spectacular. The music and sound design enhances the experience a lot too.
tbh my most recent one is probably Forza Horizon 5. I'm not really a "car guy" but nothing beats getting high and doing sick jumps over gorgeous natural landscapes in bodacious sports cars. Bonus points if your Ferrari has an anime girl spraypainted on the hood.
People already said Horizon, which is my #1 choice, but I'm surprised I didn't see anyone say Sekiro. That game is gorgeous. I'd often stop and look at the environment when I wasn't killing people lol
Chicory is an artistic top-down Zelda-style game that is not only adorable with its cute characters and world, but it also invites you to add color to the world and give it your own touch.
Most recently horizon: forbidden west had me moments that I would stop and just look the beautiful scenery. As a hardcore introvert, staying inside person I really admire such a great view.
Inside and Naissancee have a lot of moments that just gave me a huge sense of awe. They have some really haunting, yet beautiful scenes.
Thumper just makes me constantly question how the hell the devs made the game look that way.
Half Life Alyx is weird because it didn't so much blow me away with the huge things as it did with the small things. There's so many small objects and details everywhere that stand up even when you're physically shoving your face into them.
Bastion from supergiant games, most of the game is hand painted, it gives a floating feeling, and given the game is on floating islands it gives really nice atmosphere.
On the other side, the art style of Katana Zero and Hotline Miami is dirty and distorted, but I really dig that style . Probably wouldn't work with standing still part, but in motion they are works of art.
Monster Hunter World is five years old and holds up great.
bask in the sun halfway up the Ancient Forest with a Tobi-Kadachi (giant white electric flying squirrelsnake; chill until you hit it)
climb up to the top of the Coral Highlands cat colony and watch the sky jellyfish float by in the sunset
share a hot spring with snow monkeys in the Hoarfrost Reach
They did a great job of making the maps feel like a living system that goes on while you're not there. (Sadly, this is much less true of the newest MH game, Rise, where the maps are full of traversal puzzles but the wildlife pretty much all exists only to attack you.)
My recommendation list is going to be a wild mix of different styles. Basically aynthing in my Games Library that I find visually appealing...
Gibbous - A Cthulu Adventure: While it isn't my favourite point&click (that price goes to the Deponia Trilogy), it's by far the most beautiful I've played up to now. The attention the devs paid to detail is astounding. The animations are perfect. In other words: A work of art.
Euro Truck Simulator 2: I might be an exception here, but to me the main selling point of this game is the scenery, not the trucks.
Elite: Dangerous: Most of the times this game looks utterly boring. Sometimes however, you catch an exceptional sight. Here's a screenshot of an eclipse in a binary system, as seen from an icy moon of a gas giant (behind which the primary star is hidden).
Space Engine: Same argument as for Elite. Most of the stuff is boring. Sometimes you find an exceptional sight. Also, Space Engine isn't really a game, but rather a "beautiful picture generator", as there is no real gameplay as of yet.
Dwarf Fortress in ASCII mode: The ASCII "graphics" are a work of art on their own. Especially the animations. And the best part: The ASCII version can be downloaded for free, while the (imho less beautiful) graphical version costs money.
Pyre: A mix of Visual Novel and Sports Game. The backgrounds and characters are beautifully drawn.
Beat Hazard: The colours of the effects are stunning.
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.
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.
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.
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.
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:
I played Ratchet and Clank: A Rift Apart recently because it was available free on PS+ and it is the most gorgeous game I have ever played in my life.
The graphical capabilities are astounding, the aesthetic is pleasing, and there is charm out the wazoo. You can't look anywhere without seeing something interesting making use of all that fancy graphic tech. I kept it installed despite 100%ing it just to mess around with the photo mode.
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.
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
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
