Today I was working on a small pseudo economy for the mod and after at least 5-7 hours i'm nearly done.
The new / advanced industry works like this:
1.Miners harvest RU and gain a basic income for harvest.
2.Ore is stored
3.If refinery is available: ore is convert to minerals.
4.Minerals are stored.
5.If assembly-array available: minerals are converted to income.
It's stored all in your main store, no industrials travel between the Stations.
I thought it would use too much CPU and slow down the gameplay too much.
If you reach 1000000 ISK your additional money from harvesters will be turned into Ore to prevent ISK loss
take a look at the new screens.
