The buildings, the fertility system, the population system, the decisions tab, crusades, diplomacy, marriages, the units, and more.Īll of that together gives you a completely new game which I enjoy so much :D The mod is going towards the directions of a sandbox game (you can release a conquered fief and create a vassal !!!) which is something that I always hoped for in a Total War game. So I opted in as a tester and played the latest version of 1212 AD overhaul.
