Not necessarily. I used a collapsed Mars colony as a major plot point. It was supposed to be up running and the new utopian home of mankind. Instead it was a handful.of skeletons and a bunch of autonomous construction bots building building, waiting for the colonists to arrive.All of the above EXCEPT space travel, I think once ypu’ve got space travel its no longer post-apocalyptic, since space gives respite from resource scarcity.
So could the PCs choose to get on a ship and leave - head back where they came from? If so then in my mind its not really post apocalyptic. Even if they cant, they now have a colony ready for them to explore, exploit and populate - imho thats space exploration/colony building rather than post-apocalyptic.Not necessarily.
