Your most important cities also have raw materials (shields) available. Forests naturally
produce a number of shields, and Hills and Mountains can be mined to produce good
quantities of raw materials. Some special natural resources—Cattle and Whales, for
example—increase the shield production of a square, as do most strategic resources (see
“Special Natural Resources” in Chapter 7: Terrain and Movement for complete
details).

The importance of commerce (and the resultant taxes) in generating income and the
funding for researching civilization advances can also make a location an especially good
site for a city. Rivers, lakes, and coastlines are naturally rich in commercial potential.You
can even generate commercial income from squares that naturally produce none, if you
build roads to encourage trade.

If a square within your City Radius is outlined, it is being used by—and benefiting—
another city. If you own both cities, you can flip between City Displays to adjust pro-
duction in each to the best benefit of both locations.
