A simple building game is good. But JNO can also be a great exploring game to differentiate it from other rocket building game.
Why "new" origin? What happened to the "old", the previous space faring civilization before the Droos? Did we inherit their technology? Are there any lost notes, voice recording, monoliths, spacecrafts, landers, ancient cities, etc. out here that tell the story about the past and maybe the inevitable future?
The playerbase will self-explore and self-interpret the lore. Maybe secretly releasing more and more hints in each updates.
Better yet, making the lore items only available in career mode, so that people will only can find out the artefacts if they play career.
