In the next 14 turns (t128-t143), I meet the Pop-music group the Buddhi-Five, they are: Suryavarman II, Lincoln, Alexander, Pascal II and Julius Cesar. The other 50% of the game has begun. Civ 4’s diplomacy system is incredibly successful not only because all the leaders have unique character but also because their character is designed with some simple character variables: WonderConstructRand (priority to build wonders), BuildUnitProb (priority to build units), SameReligionAttitude, DifferentReligionAttitude, etc. These factors help us understand the behaviors of an AI and predict the future of the game. AI’s characters should be learned by heart for an Immortal player. Another chart is simple but very useful as well for an Emperor/Immortal player: at which attitude AI won’t DoW you. It’s extremely important in particular for a no s/l play, in which risk should be minimized at the most. To know your rivals is already sufficient to help us defeat Immortal and below, but in Deity, you need not only to know them but to USE them. That needs another chart: Trade Relation. If defines all levels of relationship needed for a trade: OB, resources, bribery, voluntary vassal, etc. Among them, the most important thing is the attitude needed for bribery of DoW. So, I have now 6 rivals who are very different from one to another, but the first thing (and the most important one) I look at is: WvO:if Friendly (to you) can be bribed to DoW a Cautious (to a third-party) AISury:if Pleased can be bribed to DoW a Pleased AILincoln: if Friendly can be bribed to DoW an Annoyed AIAlexander: if Cautious can be bribed to DoW a Pleased AIPascal II:if Friendly can be bribed to DoW a Pleased AIJulius Cesar:if Pleased can be bribed to DoW a Pleased AI If we ignore the other factors, we can see easily who are easy to control and who are not: Alex > JC = Suryavarman > WvO > Pascal > Lincoln. Then we’ll try to integrate the other factors: inter-relationship between them, scores, power, and the most important thing: tech situation. I'll talk about these in the next post. Here enclosed the no-war attitude chart (made by royanstar) and Trade Relation chart (made by gowang). Many thanks for the share of royanstar and gowang on Civclub forum! No-war attitude chart: Spoiler : The lower the figure, the higher the risk of DoW. 100 means there is no DoW probability at this attitude. Edit: Several explanations about the Trade Relation chart enclosed: If the trade is only between AI and you, the relation displayed in "to you" section is AI's minimal relation towards you to make the trade possible. If there is a 3rd-party involved, the relation displayed in "to a 3rd-party" section is AI's maximum relation towards this 3rd-party. Example: Alexander: in the "Go to War" Section, it's Caution (to you) and Pleased (to a 3rd-party). That means: if Alex is Cautious/Pleased/Friendly towards you, he can be bribed to DoW another AI towards whom he feels Pleased/Cautious/Annoyed/Furious.
