Here are the battle and campaign AI files incldued in Lands to Conquer Gold for those who want to use them.
Battle AI
Battle AI.zip contains battle_config.xml, config_ai_battle.xml, descr_formations.txt, descr_formations_ai.txt, descr_pathfinding.txt.
Features of Battle AI:
-Increased use of flanking by AI.
-AI no longer passive in field battles v missile heavy armies.
-Better AI in siege battles.
-Better pathfinding for AI.
Campaign AI
Campaign AI.zip contains descr_campaign_ai_db.xml, descr_diplomacy.xml, descr_faction_standing.txt.
The ai_labels in my ai are:
catholic
islam
default
papal_faction
slave_faction
I recommend increasing the movement points of name characters and generals in descr_character.txt as it helps the AI out.
Features of Campaign AI:
-Stronger alliances, and allies which help each other more. This results in alliance blocs forming which also change over the course of the game.
-More logical changes to faction standings. So you and the AI will no longer always end up terrible and untrustworthy.
-More logical diplomacy, so it is now a more useful tool in the campaign.
-Rarer Catholic - Islamic alliances.
-Better AI sense of survivability. AI factions are more likely to want peace/vassal if being beaten/beaten badly.
-Better AI garrisoning settlements, and use of forces to guard it's borders.
-More aggressive AI v rebels, so the AI expands much better early on and so the AI can create powerful nations.
-Better AI invasions. It will now build up more before attacking, and attack with more stacks, and stacks which have more units in them.
-Catholic factions less likely to attack each other, but still plenty of wars going on to give that Total War and Medieval experience.
