Here is a collection of some things in W3.

Yeah, this has to be a Naughty Dog / Rockstar thread. The detail put into a game like GTAV is almost incomprehensible.
When in-game sound effects harmonize with the level's music.
I watched a recent video that demonstrated this phenomenon, using Mario Odyssey as an example: https://youtu.be/U5-YDxH6It8
This. He's even nice enough to give you a small glimpse into the secrets of existence, thus giving you a nice permanent boost to your wisdom. You can also use a fake name during many dialog situations throughout the game. Doing this leads to some strange eventsIn Planescape: Torment you can meet the personification of the letter O in a bar and chat with him.
The wind in BotW it's insane, it determines where the clouds go, how the grass move, and depending on every object's weight, how the object it's affected by it.
Saiyoris Hands are bloody/hurt. Indicating - although she hung herself - it didn't quite work like it was supposed to. So she war hurting her hands while trying to loose the rope around her neck as the survival instinct kicked in. It is an insane little detail I guess.
Too bad the rest of the game doesn't keep up with the Tanker part. It's like the team spent 90% of their time developing that level and 10% was for the Raiden parts of the game.
This type of detail where the content of a letter actually exists in the world is quite frequent.
That blew my mind when I first watched that video. MGS2 amazed.
