Nothing in the description that really specifically says DF or Rimworld to me, despite having tried the former once or twice and having played a fair bit of the latter. bit of Rimworld. Seems a bit of shame that they didn't bother to mention DF-9 at all, given there a number of features/mechanics stated that sound very much like it. You know like space junk/meteorites causing damage, passing ships docking to drop off new crew/allow pirates to break in, minable resources that you have to send people out to get.
Personally I don't think DF-9 needs remaking, The only problem other than maybe bad pathing that I recall was not much of a drive to keep playing past a basic base that was sort of stable.
