That being said, could you make a tech tree of your design which would involve coming back to technology and higher from locked and barbaric state after World War? Notice that it's not "reinventing stuff", it's rather "discovering lost", so there may be interesting choices (and maybe a split of tech tree in two or even three "major" branches, like FFH2 requires, could be nice, i.e. "restoring humanity", "robotics/cyber" and "mutation"). I would like to see your ideas.
