I quite like playing the evil overlord/lady so this was right up my alley. There's quite a big variety of events and the ability to manipulate the other 3 kingdoms against each other was very fun. Good dark humor too (unicorns? Didn't I kill them all last time?)
A suggestion, some more art pics would greatly help with the walls of text. Not even a lot of variety needed, like each time we recruit troops the game should show up some generic soldiers of the respective type, or when we raise influence it shows some kind of shady dealings with the respective faction.
Something particularly unexpected/funny was that the game told me the new human king was hot stuff and that my following assassination attempt completely failed, then in the final battle his lords just instantly submit to me and execute said king. The Dwarven King was a bit smarter to kneel himself, then some elves joined me but their monarch actually tried to make a stand and was crushed anyway.
Also I had recruited some dark knight as a hero, then seemed to lose him when going into an expedition to some ruins when it described him falling down a bottomless pit trap, however I could still make him steward of the human kingdom?
