I dont think that it was a good idea of Firaxis to include in BtS the HRE instead of Poland. The HRE already is represented by France and Germany and DID NOT EVEN EXIST when Charlemagne was king of France and Germany!
I think that to have HRE is a very bad choice from the point of view of historical accuracy and gameplay too. Even Holland was put in the expansion, which is smaller and, especially in the Polish golden age of the XIX century, probably not of the same cultural impact as Poland. I dont say that Holland should not be included, everybody knows that they invented the windmill and other engineering concepts that are important for civilization, but the HRE really nobody understands since we already have France and Germany!
Lets hope we still have time to convince Firaxis to correct the big mistake they made with BtS!
