Bretonnia is a lot of fun. Their infantry sucks, well the Fay Enchantress has some nice buffs for the pilgrims and foot squires, but once you get Questing Knights and start fielding full cav squads, battles are immensely enjoyable. Bretonnia just got some updates to their tech trees and other tweaks with the Tomb Kings patch so now it's a great time to play them. I played with Louen Leoncoeur as my faction leader and he's such a beast in battle. I got cornered in the early game by two Skaeling stacks and everyone but Louen died. He would not break at all. I think he had 400 kills alone. When you confederate Alberic, park him in Marienburg and watch the money flow.
I appreciate the SFO endorsement,
@Rational Poster. Having a lot of fun with it and it's not too difficult. I like some of the little event pop-ups and I almost got Khalida wounded because I was fighting a siege battle and beelined her towards the Vampire Hero and it really showed me how strong the lords and heroes are in this mod. Total pyrrhic victory in the end. I'm reallly digging the longer battles and Khalida's unique quest battle with this mod was absolutely epic.
