I think the idea of crashing again after you escape one planet to start a newgame+ was mentioned, but I thought it would be cool if that was taken a step further and you get to design your ship and build it as you go along. It could turn into a sort of FTL/RimWorld hybrid where your ship moves to different areas, until you accidentally crash again and are stuck. It is a thrown together ship after all, can't expect it to take you very far. End of the game would be making it back to civilization.
