AI logic modifications (limited to high difficulty)


Major Empire AI
As the attacker
More keen on capturing points, killing long-range units and killing units that capture support points
Melee units will protect archers, seize control areas to form positions, be more interested in high points and forests, and will put a lot of effort into liberating support points
They will be more inclined to engage quickly, and the battle damage ratio will be considerably reduced.

As a defender
Prefer to deploy on high ground and fortifications rather than where the flag is, and pay more attention to the distance from the attacking side
Defensive points will be critical to them, and will prioritize using long-range units to consume them, caring about the battle damage ratio
Support points are of average priority, more interested in fortifying plots
Prefer to keep distance from the enemy

When diplomatic relations are hostile
AI's propensity to advance, siege, garrison, raid, and steal will be close to full value
When diplomatic relations are on alert
Garrisoning and territorial occupation will still have a high tendency
When diplomatic relations are friendly
Only garrison tendency will be present
AI diplomatic attitude logic
AI attitude logic overhaul
(to simulate a more reasonable diplomatic immersion, different attitudes correspond to different decision tendencies in different aspects)

War aspect

Inferior (fear, jealousy, awe) very low hostility, almost no interest in all aspects of military action tendencies, jealous attitude may cause not low hostility while obsessed with stealing your territory, while awe attitude has no military activity tendencies at all and no hostility


Negative (aggressive, full of hate, hesitant, suspicious) aggressiveness will initiate all possible raids, interest in siege and theft, hostility is also very high, full of hate, all military actions are full (except theft) and his hostility towards you will be at its peak. Although the sluggish attitude will have some hostility but basically will not initiate offensive behavior siege and theft is a pipe dream. Skeptical attitude of attack behavior is more random, but also will not have too much probability to attack the city.

Neutral (hesitant, need help needy (needy Chinese can be translated as need help or greed), disgust) hesitant almost will not have all the attack behavior, greed low hostility, will not have most of the attack behavior, but the theft is fully committed. Aversion will have some probability of initiating a fight.

Positive (pleasing, pleasant, friendly, close) will have essentially no military actions, with a decreasing negative for military tendencies as goodwill increases

Unknown (not affected by this)

Superior (condescending, protective, domineering) condescending, low tendency to initiate battle raids, average hostility, will steal territory at will Protective, will not besiege the city to raid, basically will not have attack behavior. Hegemonic, reckless aggressive behavior and hostility are in a high state of love.

Diplomatic (each agreement three tendency levels: initiate, will agree, bargaining)


Military agreements
Disadvantage:Fear will agree to sign a covenant to supply, bargaining to agree to stealth intelligence sharing. Jealousy then only bargain to reach mutual non-aggression, fear can even bargain for the highest military authority

Negative (aggressive, hateful, hesitant, suspicious): aggression will likely reach mutual non-aggression and will launch nuclear strikes. Hateful most of the time tend to mutually assured destruction, may be able to reach ordinary open war, the rest are allowed to skirmish, can bargain to reach mutual non-aggression

Neutral (hesitant, needs help, disgusted): hesitant is easier to reach non-aggression. Need help is more difficult to reach non-aggression, bargaining is easy to reach alliance, aversion is difficult to reach non-aggression, skirmishes may be extremely high.

Positive (pleasing, pleasant, friendly, close): pleasing is easy to reach a military alliance. Close is even possible to reach the highest cooperation. Friendly can bargain to reach shared stealth action, pleasant will initiate non-aggression and may bargain to get to join the battle.

Superior (condescending, protective, domineering) will not agree to any military demands, and the likelihood of bargaining for non-aggression is very low. Protective, on the other hand, is happy to enter into a military pact, has an additional consent index for joining the battle, and bargains for the possibility of logistical resupply. Hegemony will only lead to total war and possibly even unleash mutually assured destruction.

Cultural agreements

Inferior (Fear, Jealousy, Awe): All but the Jealous attitude can make cultural pacts through normal or bargaining. Jealousy will always keep borders closed. Fear makes it possible to reach a "faith as high as the sun" (conversion to a religion).

Negative (aggressive, hateful, hesitant, skeptical): hesitant attitude makes it possible to conclude open borders by bargaining, the rest close borders by default.

Neutral (hesitant, needing help, averse): both have the possibility to reach the border opening by bargaining, needing help attitude has the possibility to bargain for permission to enter the city.

Positive (pleasing, pleasant, friendly, close): pleasing attitude can be bargained to enter the city, close can be bargained to reach "the same supreme faith as the sun" (conversion to religion), friendly bargain can be bargained to sign a cultural treaty, pleasant can be signed to open the border

Superiority (condescending, protective, domineering): condescending bargaining can lead to open borders, protective bargaining may lead to entry into cities, domineering always closes borders.

Economic agreements
Inferior (fearful, jealous, reverent): fearful attitude has the possibility to initiate luxury trade has the possibility to bargain through free transport. Jealous attitude will actively destroy trade routes and will tend to stop signing new ones, need to sign luxury trade by bargaining, reverence will initiate cheap trade will accept sharing of resources.

Negative (aggressive, full of hate, hesitant, skeptical): the first two attitudes will not bother to sign economic agreements, the last two attitudes need to bargain to try to sign luxury trade.


Neutral (hesitant, need help, averse): the hesitant attitude is prone to sign luxury trade, and bargaining is difficult to sign all resource trade. Need help attitude will initiate all resource trade, can sign cheap trade, bargain to sign free transportation. Disgusted attitude requires bargaining before you can agree to all resource trade.

Positive (pleasing, pleasant, friendly, close): pleasing attitude will most likely initiate luxury resource trade, will gladly accept cheap trade, need to bargain to be able to accept free transportation. Pleasant needs to bargain to sign all resources, friendly and close will gladly accept free transportation.


Superior (condescending, protective, domineering): condescending attitude will accept luxury trade need to bargain to unlock all resource trade. Protective will initiate all resource trade, will accept cheap trade and need to bargain to unlock free transportation, overbearing needs to negotiate to unlock luxury trade.

Information protocol:
Inferior (fearful, jealous, reverent): fearful attitude will not sign information agreements, jealous attitude will sign technology sharing, reverent attitude will even initiate technology sharing.

Negative (aggressive, full of hate, hesitant, skeptical): they are not willing to sign any information agreement

Neutral (hesitant, needy, aversive): the first two can sign a sharing map, the aversive attitude cannot sign any information agreement

Positive (curt, pleasant, friendly, close): curt attitude bargaining can be signed to share vision, pleasant can be signed to share maps, friendly and close can be signed to share technology.

Superior (condescending, protective, domineering): condescending attitude requires bargaining to sign a shared map. Protective is willing to actively share maps, sign shared vision or even bargain technology agreements. Hegemonic refuses all information agreements.
