This circle will require
Water, Wheat, Aluminum, Lumber, Marble, Iron, Cattle, Sugar, Pigs, Spices, Uranium (ME), Fish (ME)
This will grant you Beer, Construction, Fast Food. Which is a must need for any civilization to thrive on.
This is long-term, and if you want to quit the circle, we need a week-before notice. Otherwise there may or will be a penalty. But than again, why would you quit such a circle?
