Civilization – How do the leaders’ AI personalities work

civilization-4civilization-4-beyond-the-sword

Montezuma and Tokugawa seem to be very prone to waging war on me, just as Gandhi is always very friendly, so I guess it's safe to assume that the leaders have different personalities. My question is:

  • Does each leader have a pre-made
    AI personality script based on its
    historical counterpart? (for example, Gandhi being a pacifist)
  • If not: Does
    the AI play to the leader's
    traits? (for example, choosing to be
    on the offensive with Montezuma
    because of the Aggressive trait)

Best Answer

They have a pre-made AI personality script, that gives them their unique behaviour. To give an example, Catherine is the only leader that might declare war on you even if you have the best (Friendly) relationship, other leaders will never do this. She is the backstabber.

Of course this behaviour will also match their traits more or less, so Montezuma, Shaka or Napoleon are more likely to go into war (actually you will see them fighting most of the time), while Hatshepshut, Gandhi or even Mansa Musa will attack you quite rarely.
