If you can defeat the AI like that, maybe one day you'll be ready to move up to online multiplayer.
War is not just about killing the other person. Its also about forming alliances to make fighting easier and to gain help when is needed. I form alliances for trading porposes, mostly. But they will all die sooner or later, whether by me, or by anther AI, usually by me though.
thanks for the help, everybody else.
