A simple mod that replaces the German Reich with the Holy Roman Empire. The tag for the Holy Roman Empire is "HRE". The other countries in the game are Prussia, Munster, Nassau, Bavaria, Wurttemburg, Baden, and the Dutch Republic.
Release 1 Adds Holy Roman Empire, Prussia, Munster, Bavaria, Wurttemburg, Baden, changed Netherlands name to Dutch Republic, and makes Hungary create Austria-Hungary.
Is it competeble with the 1.3.3 version of the game?
No. But I feel you though.
