Correct. But the picture in the image with the colors are mounted teutonic knights. Medieval 2 Total War Teutonic order shows them well.
The red cross is the Templar knight as shown in england and france.
The black cross is the Teutonic knight, which is a seperate order for germanic countries.
Knights of Saint John have a white cross on red or black.
Knights of Santiago have a red cross (different cross) on white.
It does not have to be entirely German. If it is the majority or the ruling class of it, it can be portrayed as a civilization in its own right. You can read everywhere, that the German order existed as a state for 700 years. Therefore he can represent a civilization in the game.
Also Im pretty surethere are only 3 more Euro civs then Asian. Seeing its a medieval game it is pretty generous that there are so many other civs also from Africa and Americas.
This would be incredibly disappointing. It should be an Animal Nursery, like in SW Galactic Battlegrounds, or a Mill + Market combo building.
Training Herdables will never be seriously used.
Maybe the new polish special mill will be like the building in Star Wars Galactic Battlegrounds (I think it’s called a nursery) where herdables can be garrisoned and they produce a small trickle of food like relics.
