(It is translation from russian, so the names can be some mistakes)

thanks for the info Nike .i think most of the names are correct. (except: Malopolska is Lesser Poland.)

nice to see Kingdom of Prussia is playable. the game contains all the important states of that time in Russia, Poland and the Great Lithuanian Princedom and some other lands near them.

I think (Grand) Duchy of Lithuania is a more common form in English...

Even without tactical combat the game can be fun but with a tactical combat system like King's Bounty (or something similar), it would be a must buy!

I think the maker wants the game to be a grand strategic focus so basically tactical gameplay will have unwanted impact on the time spent for multiplayer gaming ? :)
for casual gamer like Total war should be a hit to have tactical battle, but the grand strategy game is always fun way to do things in a long run without micromanaging a battle...
