I play on 'king' , mostly because I'm still exploring the intricacies of Civ5, and I have a question for all the players who play on the hardest settings. Basically, I don't war-monger I like to build my empire thru diplomacy and city-states and economy. However, there are times when war is inevitable. Usually its because another Civ declares war on me. When this happens I build some units and prepare to defend myself. Then the AI attacks me with warriors and spearmen, and I'm clearly capable of building knights, swordsmen, and trebuchets. The AI stands no chance. Does this happen on harder difficulties? I have read that the AI needs tweaking as far as war goes, but why would the AI declare war on me and have access to horses and even Iron and still send the weakest units against me. Then I capture 1 of their cities and they suddenly offer a truce.
