OK, the Trade AI needs to be fixed and improved BADLY.
I have 20 Chromium sources in operation. I have 620K Chromium stockpiled. I have ~300 Freighters in operation, all modified to the same 10 Bay design.
AND! Not even a single unit of Chromium in transit after 6 game months of bases/worlds all screaming for Chromium. And the Advisers want to run smuggling missions for Chromium?!? What the bloody hell are the Freighters and Stockpile for if the Private Sector and Advisers are too damn stupid to use them? Grrrrr....
Things to remember:
1. Every starport requires a certain amount of resources. The more starports you have, the more strain on your transports. My latest game has 40 colonies and
1 large starport at my capital, no other starports at all...and no resource shortages. Any abandoned star ports I acquire are retired to prevent problems. Once I am certain I have enough resources stockpiled and enough mines/freighters to keep up with demand, I will build a second starport.
2. Every starport will put resources in reserve that can not be moved. Obviously the more starports, the more reserve and the less you have to distribute to other places. In times of 'shortage' the starports will always have priority, so they get their shortages filled before anything else, and causes delays in other bases/planets.
3. Every time you upgrade mines, they require resources. Keep mine upgrades to a minimum if you do not want to have shortages due to that. Mines are low on the delivery priority list, so every time you upgrade it may take a while to get them all done.
4. The two most important resources you need are caslon and hydrogen (since they are your fuel sources)...followed by gold, lead, steel, iridium, chromium and carbon fibre (by my estimates). With Caslon and hydrogen being fuels, you can see you have need for very large stockpiles of them. The first thing I do in a game is order 4 gas mining stations to get caslon and hydrogen stockpiles started.
5. If you do run into a shortage, you get behind all around as the freighters attempt to fix shortage one and lower the priority of other needs. Its always best if you can prevent shortages in the first place.
6. The most important principle of all this:
DO NOT EXPAND TOO QUICKLY! I cannot emphasize this enough, do not grow your empire faster than your economy can deal with. Each expansion brings in new planets needing resources, each new starport requires resources, each new base of any type requires resources, and all that requires more freighters...which have to be built before they can start transporting. You need mines before you need new colonies, starports, and defense bases, period.
