The default Elite AI are easy to kill

[Jeremy]

I don't buy steam version of WKB as I have the original game.
Well, my route for complete the campaign: my fourth stage was the Liguriensis and the final complete stage was Rusland.These two stages are the most difficult to clear.Liguriensis have one AI with basic developed economics and militaries and have one allied AI.For Rusland, you are surrounded by enemies.But most stages I used the same strategy to beat the AI.
Economics: 30 farms and 20 materials hunters.
Militaries: >40 Squires(with some for defense role) and >30 spearmen (for defense role only)
Archers are garrisoning the forts.It depends on the number of forts you construct.
Order minimum 35 Squires attacks the enemies.Always stay around the enemy keep or manor and aims at Wagons.AI are set that if there is no wagon for transporting resources, they will destroy the villages(that's stupid setting comparing with WK.)When time is going, all peasants are returning back to change as millitaries. It's the best time to clear all peasants for avoiding ememies' economic growth.Use building to hide from enemies' forts attacking.After you beat all units of all AI, then you can use sapper to build up some powerful tools to eliminate enemies.Then done.

I never completed compaign or a battle against AI when I used to play this game many years ago. For me AI was too dificult. I can't be general and major at same time! Enemy build their economy and millitary way too fast! So I played only sandbox mode and fought only barbirians. There is no guide or proper wiki with tips and strategy on google or youtube. I wish there was an easy mode...

easiest skirmish - village, spend your 500 food on 10 peasants - rush chop wood, sell village, build shop, sell shop, build tavern - once you have enough wood for the tavern collect what gold you can and build mercenaries, fire the enemy village, if your quick enough they wont have a tower up
forgot to mention i send my peasants and the cart in as a diversion
