I typically exterminate and use the money to improve my cities in the core of my conquered lands. This way, I am always strengthening the center and growing outwards while limiting the enemies ability to counterattack and reconquer. Plus I can quickly move my army out and leave behind a skeleton garrison.
Hey, thanks. It is good to know that I am not the only one to use this strategy. Do you also find it is nice to have 2-3 generals with really high dread?
