@Imperious:
So if you were in North Carolina and bought a gasoline station and hired Gomer to serve the people at Mayberry your not making much of a trade, but if you instead went to Raleigh, your business would improve.
Sure, but since there is no anti-gouging law in NC, Gomer could charge as much as he wanted since he was the only station in Mayberry…
But on a more serious note, I remember way back someone had put together an idea for each territory to produce it’s ipc’s in it’s territory and then they had to be transported to a factory to produce, so you could build factories where-ever, but you had to get the materials there. On land they could move, but over water they needed a cheap 'merchant ship to move them. No ships, no movement of goods to factories. More detail in the factories could be interesting time to put more detail in the raw materials production.
