If this has already been answered before, then please direct to me to the thread if you know of it.
I've been playing a constantly over the past week, and yet consistently the only way I know how to find out which industries to build is through trial and error - build it, see if it makes decent money, and if it doesn't then uninstall and install the next one. Surely there's something I'm missing. In addition to that, an industry on one planet sometimes is a one-hit wonder and makes me loads of money, and yet the same industry on a different planet may only result in a loss from the upkeep with no exports.
Knowledgeable people of Starsector, elighten me.
Edit: Alright I've been staring at the screen trying to crack the code and solve the rubix cube this game is throwing at me and I now understand that the demand, the amount I can sell, is directly determined by how much my colony needs. If my colony needs 5 fuel, I can sell 5 fuel to it. Now, with that said, why am I making 3k from my light industry and a different colony is making fat bank with the same amount of demand and little change in accessibility and populations?
Edit 2: I can conclude Starsector is out to get me and doesn't care about demand and income, or the logistics of it, only driven by it's thirst for my blood and to make my wallets suffer and my head hurt.
