I want an AI with the following:
- Knows when it is being beaten and sues for peace.
- Knows when it needs strategic resources - prepares an army and then has a go at getting them.
- Can determine the difference between global superiority and local superiority in military strength.
- Knows how to do Normandy landings and not a constant stream of Bay of Pigs disasters!
- Tries to be nice to you when you are bigger or more advanced (so that you help during a war - at the moment the AI comes to your door asking you to attack an enemy when he has been stabbing you in the back for the last 1000 years!).
That is all I can think of at this stage for the high level stuff.
Diplomacy (just quickly)
- My diplomacy advisor being wrong (advisor - "I don't think they will accept that proposal" send proposal and advisor comments - "Holy cow they accepted!")
- Counter proposals from AI - ie "I will accept your proposal for an extra 100 gold" or "How about we swap the gold for some coal as my empire could really use that right now(!)"
- Germany says "France is being a pain in the butt right now - how about we have a military alliance for the duration of the war and lets do a surprise attack in 5 turns."
Well I guess I can dream...
