+    - turn-based. Everyone does their trading at the same time, and then flies to the next station
+        - instead of making journeys take longer, for game-sake, longer journeys just cost more fuel.
+        - "faster" drives are actually just more fuel efficient
+    - the prices of goods are supply/demand based on quantity produced/consumed at planets/stations
+    - the prices/goods available at a place are only visible to those who are in the station
+    - stations may build "reputation" prices for repeat suppliers/buyers.
+    - players can trade with each other while at the same station
+    - certain stations have shipyards, with mortgages available for trade-in/upgrading ships drives/storage capacity, etc.
+    - all systems have a safety rating, indicating likelyhood of piracy. High risk systems often have higher profitablilty
+    - AI station trading agent for haggling deal-making?
+    - transport contracts available at stations randomly.
+    - in a system, you can fly out to the asteroid belt and try to buy from miners directly, but it's a gamble on even finding any of them.
+    - game ends when someone pays off their ship's mortgage.
