I love building settlements but its a little barebones right now.
I hope Bethesda makes a more robust settlement DLC that will enhance the experience. They could do so much with it and even give storylines based on settlements . Just make them random. You could even have NPC settlements that you can raid and that raid you as well.
The settlement building could be a great part of the game if done right. Id also love some tweaks to the settlements like a better inference to give them jobs and even the ability to name them, so we can keep track of who is doing what.
