I like playing on worlds where expansion is constrained by habitable planets and large spaces in between worlds to make exploration and colonization difficult. I.e. huge universe and rare planet settings.
I'm hoping to force a game where you have to fight over key planets in order to get the range to expand.
However I've found the range of ships is so easy to scale up it really makes no difference. It seems like ship range is really not as relevant or interesting as it could be with such large ship range. I dont mind range being researchable later on but it's so immediately available that who cares.
Is there a setting I can try to change that will make the universe a little more sparse with strategic geographies?
