The Evolution of Heat Signature in Star Trek: Voyager

heat signature has an unusual modification of the roguelike structure where player characters have permadeath but the galaxy's state persists. How did you come to this format do you think other future roguelikes would benefit from adopting this design element? I don't think heat signatures are run based game because it's not a sort of fixed chunk of content that you try and complete each time it's more of a worldy feel.
