A couple of months ago a thread complaining the AI is too easy: (Hidden Content) This thread is evidence suggesting: Quote from J.T.C. Roulain: “The only nations on the map that are worse than AI are the players themselves. ”
This is a joke. Please actually make the AI a threat. Afterwards, please actually make players a threat. AI do not produce too many units. They don't produce enough units and the units they do produce are inappropriate, ineffective, and (if at war) are immediately sent to die. The only nations on the map that are worse than AI are the players themselves.
Along these lines, perhaps change how propaganda offices work by removing the direct modifier to morale and replacing it with a modifier to "Distance from Capital" or some variation on that concept? If the capital is lost, the propaganda offices would cease to function. Just a thought.
