Again, why is the French civilization refered to as "French Empire" when they are using just "Russia" as a name for the Russian civilization? If they really wanted to avoid associating with modern existing countries, I bet that distancing themselves from Russia and using a different term would have been something they wanted to do (especially considering the current war in Europe).
I find it great that they just went with using the name "Russia", as they have done with Spain, Greece, Egypt, America, Mexico, etc. They should really considering renaming the "French Empire" and just go by the name "France"
