So with all the discourse here again I decided to just make a mod to see how much you need to change to make the Germans either Prussian or Austrian.
You can check it out here to see for yourselves.
Simply put, I had to change a lot more to make the Germans work as Prussians. Doppels and War wagons just don’t work for Prussia, so a lot of cards affecting them had to be changed as well. I chose to replace them with Grenadiers and Dragoons, but the Giant Grenadier would’ve been a better choice perhaps.
All Prussian themed cards are new in DE so that was easier to replace or remove for the Austrians, just 4 of em.
The Austrians ended up a lot closer to the OG Germans.
Note that some card names only change ingame, didnt want to make completely new cards for stuff that just needed a name change. Maybe later.
