We need culture drift in Bannerlord

One great thing about Mount and Blade games is how they simulate a living world where things evolve whether you do anything meaningful or not. The game world is constantly changing. Wealth distribution, kingdom borders, even the people change with time. Therefore it's such a bummer that the culture of a settlement can never change. No matter what happens, even if the Empire unifies the entire continent under one banner and rules it for centuries, Battanians will always be Battanians and will never adopt the ways of the Empire.
