Fallout 4 is a really impressive game. It doesn't make perfect sense, but that doesn't really matter. I loved the sheer detail of its world, the way that you could open a door and not just find some stuff to take, but a skeleton, and a sort of visual story about why everything was where it was. I bought the art book for Fallout 4, partly to help in making models, and it shows that the sheer amount of work involved in creating the game must have been huge.
I know, there is so many little bits of 'personality' in the world that, if you were rushing through it, you would easily miss, like teddy bears on toilets with papers 'in their hands' etc.
One of my favourites is a factory where there is a big 'danger: no smoking' sign, but there are two skeletons, one male, one female just below it, with a gold flip lighter between them. Or the two feuding brothers in the marina, the notes they left and their diary entries (I don't know which one is the skeleton that you find, I guess you might find the other one dead in his boat on the map either south or north depending on which brother won? )
