They changed the worker system. All the sqaures are being worked, you get a higher percentage of the total available Food/Prod/Com based on your population and whether you use specialists. The Farmer will get you more food output. All the specialists will decrease the retunrn on the other resources outside of their specialty. So to see how all this interelates, go to the city manager screen and look at the specialist tab.
I was wondering how I can see (or if I can see) which squares within a city's radius are being worked by the citizens for resources. Right-clicking the city doesn't seem to do the same job that it did in CTP. Please help!!!
