I wouldn’t say that. If you take Fallout 1, 2, and NV as a trilogy you can see the rebuilding of society in a post-post apocalyptic story. Things change, but I don’t think they get better, it’s just that the problems take different forms. It’s actualy pretty cynical. No matter how much rebuilding happens or how many iterations of different societies are created, people will always find a reason to be at each other’s throats. You might say: war never changes.
