Blood Gulch from any of the original Halo Trilogy games.

Anything from Ghost of Tsushima.

Anything from breath of the Wild or tears of the kingdom.

If you want another CS level, Italy Inferno has a ton of photogentic spots in both Source and GO. I’m also particularly fond of Lake, but that might be partly the 500 hours of Wingman on the map speaking.

Edit: or for Valve games in general, theres the dam from Half Life, Ravenholm or the drained shores from Half-Life 2, or an overgrown chamber from Portal 2.

The first Halo

Here are two that I thought were particularly striking visually.

Brothers a Tale of Two Sons: The site of a battle between giants, where you had to navigate among bodies fifty feet tall.

Alice Madness Returns: The ice level, where you could see sea monsters frozen in the ice. (Ignore the text; I couldn’t find a better screenshot.)

Guild Wars (the original base game) made extremely good use of clear visual themes and bloom to create an absolutely entrancing visual experience. It was a pretty shit game, though.

There are a few carefully planned reveals in skyrim that live in almost all our heads (one really memorable one for me is heading into the Rift and transitioning into autumn themes for the first time).

Cheydinhal is absolutely breathtaking in Oblivion.

Pretty much the entirety of Stray - outside the village areas they put a lot of effort into dramatic art reveals.

Ocarina of time has a few excellent ones but it’s low poly and may be hard to appreciate at this point. Especially Hyrule Castle creeping over Lon Lon ranch and the frozen Zora kingdom.

Gosh I feel like I’m missing so many others… though on the topic of CS de_infero and de_cbbl were some of my favorite visually.

Any snapshot from Morrowind.

City 17 from Half-Life Alyx, specifically the part where you see the tower

There are certain points in Metaphor: ReFantazio where the characters stop on their journey and admire fantasy scenery which are essentially static backgrounds. I’d take a large print of any of those for my walls at home.
