Feel free to throw some ideas around on nations. The only thing currently set in stone is the [b]Imperial Tsardom[/b], a composite monarchical system similar to the Holy Roman Empire, comprised of "slavic"-esque states headed by the "Grand Tsar." If anyone was intending to have a slavic Great Power, they could certainly begin as the Grand Tsar. It'll be comprised of 15-20 minor NPC nations with an interesting, interconnected political system.
