Some CAI feedback according to my Polish campaign on H/M difficulty , 3 turns/year :
The pic shows pretty much I think.After only 21 turns the Europe has changed drastically.AI is agressive and attack without hesitation - for example I was forced to sign a peace treaty with Prussia to survive even when I had 2 full stack armies - I mean maybe I could win this but it would be a great risk considering 3 or 4 full enemy armies crossing my borders after they annihilated my ally - Austria in something like 5-6 turns It was great - really great beginning of my campaign - so realistic and unpredictible.In the end I won in fact - I've captured rich East Prussia and lost poor West Prussia.What really suprprised me in the most positive way was the Ottoman invasion of Russia in the first few turns - finally they sended many armies through Balkans - and it's still happening - Ottomans are finnally defending their european possessions They made one unlogical mistake however - after capturing Ukraine , they left Kiev undefended and lost it to rebels - which was like a miracle for me Summing up - CAI with the latest patch is working really good if not fantastic.Of course there are always a coincidences that are making a lot of changes in the campaign - raising or slowing the action down for example but by the way AI acts I'm sure that those only 21 turns so far were really clever CAI behaviour - making decisions and using enemy weaknesses without hesitation.
