I had a kid right when space age came out, so I don't have much gaming time and am making awfully slow progress. Just killed my first couple worms on Vulcanus to open up a tungsten patch.
Do you generally make all your planets fully self-sustaining, or do you rely on imports to get things done? In particular, oil is kind of a pain on Vulcanus (though I haven't yet gotten advanced/ regular coal liquification), so I'm wondering if I'm better off importing ingredients for rocket parts from Nauvis, or if I should just comb out some of my spaghetti and fix my oil industry here?
