What i would like to see is some dedicated AI offense and defense. 1. The capital should never be undefended. AI should have a dedicated force to defend its capital. If the Capital is a port, there needs to be a defending fleet. (I have taken most capitals and never saw a defending unit). 2. With each capital taken in a game, the other AI driven Civ's should begin to ally and begin operations against the Human player. 3. AI naval warfare needs to be fixed to stop single ship suicide runs. The AI should run around with fleets of ships to interdict sea lanes and bombard coastal armies. 4. The AI should never declare war on a city state it can reach only by ship. All land units turned into transports should have a defense. (I've seen the AI pack up nearly its entire military and send it overseas. Its way to easy to destroy transports in the game). 5. Each AI Civ needs to be programed Defensive, Aggressive or both. Depending on size of military. Thats all for now. I hope to see other suggestions for an enhanced warfare AI.
