An attempt to flesh out the gameplay through tweaked AI and an expansion of interaction options through a variety of creators' mods. A big thanks to all of them for making a collection like this possible!

Combat casualties and retreat-distance changes warfare for a more decisive experience with every battle while prisoners taken will be held by the capturing army until returning to own territories. If your Personal Champion has a Blademaster trait he can pass this on to other knights for Gold. Religious reforms can be made without holding 3 holy sites - just be on good terms with other same faith holders of holy sites (they will convert with you). Visual overhaul of map as well as more navigable rivers and historical metropolis holdings (tweak Game Rules for balance, i'd suggest Restricted conversion so only historical metropolis are in play). Request a new Realm Priest from the Pope every 10 years and enjoy multiple Personal Schemes from the Diplomacy skill tree.
More Single Combat allows you be employed as a Knight of your Liege as well as experience duels during any army battle that you're a part of (this does not function in multiplayer due to the lack of auto-pause at event popups).
