Caesar's Legion. Those that tried to rebuild after the Great War WERE DOING IT WRONG!!!! Break it down and start all over from scratch...like baking a pie, human pie mmmmmmm. There will never be peace because we're human, humans have an innate need to fight each other for dominance, Fallout will always be relevant because war...war never changes, or stops. :flamethrower: :intergalactic:
If you go from scratch you'd get something like Mesopotamia if you break it all the way down. You add a few ingredients you would get greece or rome, personally I think Greece is way way better than rome. Rome just copied and changed it a bit, that is why they took over, but without Greece there is no Rome.
I agree humans will always fight. But Fallout wouldn't always be relevant as it is for post nuclear apocalypse, eventually it would sort itself out and be something new with fighting.
