(we will go out of 1 city)
Like Timber, Gold and chemicals.
when using the max set up of a mine is like 6 mining units and 3 sale units.
but this docent cover the supply/demand for all products.
Timber, there simply ain't enough around for all products needing Timber. so you need to got some products left aside and not produce them.
thats a very big bummer
Same goes for chemical products.
Between 1 a 2 years the reserves are depleted.
mostly i play with 10 city, so u see that its very irritating that when you are setting up a production line you get the message your mine is depleted. and that every time you raise the time speed. :s and then you have to search where you whore busy before.
so its extra time consuming and very irritating
* mines need to be able to produce more supply.
* The Reserves need to be much bigger.
