I do enjoy the zen of NMS (nothing like piloting alone on the surface of a planet with the sound of the rain falling on the cockpit), but even after all those years and cool upgrades, it still feels so empty… If you enjoy tabletop RPGs and have an opportunity to play one with like-minded friends, I recommend you try Traveller. It’s all those things you mentioned, in a way, way bigger and denser scope. :) Also with actual civilizations, empires, politics, commerce, wars, fleets, etc.
