Yeah the curgens volcano right on the king did the trick only cost me about 20 turns to find and burn him. The creators should maybe remove the ally option completely for conquer only victory. Thanks for the tip
I started a new game and made it winable by conquest only. During the game I allied with the AI to my north and killed everyone to the south etc then when I decided its time for him to die since everyone else is dead I cant declare war or attack him. Hell I turned one of his cities into a volcano still no luck. So basically unless I miss something. When playing conquest only game you CANT win if you at some point ally. So I guess I'll just start a new game.</p
