I think that make the world of Fallout 4 more dead would be a good idea. I mean that the Commonwealth is full of Raiders, Gunners, Super mutants etc. By the middle of the game, you must have already killed more than a thousand of aggressive NPCs. You could get the feeling of a dead, empty world, by removing majority of all these "enemies". Feel the Wasteland more meditative or something. When you find another location on your map, and you do not expect that a group of ghouls will jump right in your face, but you wander in darkness and loneliness, searching the garbage of the "Old world" for a couple of details that you need for your settlement. Of course I'm not talking about complete removal. There are locations tied to quests etc. that are headquarters for the group, for example: Saugus Ironworks for Forged, Vault 75/95 for the Gunners and Trinity Tower for super mutants. Maybe it would make the game too boring, but it would give something new in the perception of Fallout 4. The game would no longer make you reckless terminator, who eliminates the crowds of enemies. Rather, you would get a more personal experience, while you exploring empty, ancient, abandoned buildings of the past. Well, what do you think about this?
