+We assume that each stellar system has all the energy and protons they
+need so they can transmute elements.  The products of a stellar system
+are "spices", biomolecules, which require planets to have life, and art
+which requires sentient life.
+
+So a planet has, let's say, a bio-capacity, the maximum life it can
+sustain (for whatever factors, temp etc.) and the basic mechanic is to
+seed lifeless planets with life (using fast cheap robot probes/drones)
+and then collect and trade spices.
+
+Because acceleration is so expensive, we have "gates" that throw and
+catch ships for sentient beings to travel.  That way the ships don't have
+to carry mass to eject for delta-vee or fuel to eject it, and I imagine
+that dust and such is swept out of the regular routes.
+
+But it's expensive to build a gate and you have to bootstrap.
+
+So you start with a home system, two seeder drones, and one
+ship-of-the-line for defense and you know, to have a ship.
+
+You send out the drones to explore and bootstrap your local economy, fly
+your other ship around to do...?  Fun side quests?  Allocate build power
+to:
+- more build power
+- seed drones
+- ships
