O.k. so you have decided to finaly unleash your fury on the zulus. But where do you strike? In WWII the invasion of Russia failed because Hitler couldn't decide between capturing Moscow (Great wonders, factories, universities Etc..) and driving down in to the russian Oil fields. I like to aim directly at the resources, but are some more important than others? is it worth diverting your attack from the enemy capital in order to capture his coal reserves? Just how important is oil, The AI places a great deal of emphasis on oil resources, (I once launced a war against the russians to get hold of the oil in the middle east and the whole world declared war on me! Up until then I had quite a good reputation as well). Its almost impossible to trade extra oil from an enemy civ, even if they have two extra!
