Doing something very wrong....
I have enough gameplay under my belt to have grasped all the basic principles. And I have gotten some games to the 300+ turn mark (on easy), with 4-5 towns all doing well. But they all end the same: which ever other faction is the bully boy declares war on me and easily wipes me out. He sends a single army that exceeds the entire protective army I have spread thinly across all my cities. (I can't support a larger army, and if I try to keep them all together, they are never in the right place at the right time.) I feel like I'm making some kind of basic mistake. Any suggestions? I'm sure this has been asked before, though I did browse... feel free to refer me to a thread where this is answered!
