's idea that each TC can chose a nationality (Austria, Hungary, Romania, Croatia, Bohemia, Gallicia--can rebel into Hungary, Romania, and a new Serbia) , and so each TC spawns a specific unit whenever you receive a shipment, and can build TC's in the Commerce Age, though they have a peasant limit ala the Turks that needs to be increased at the cathedral.
Take the War Wagon and Skirmisher from Germans, but the rest is stock, excelling with their elite shipment units, who can be sent infinitely in the Imperial Age. Has Maria Theresa as their personality>Poland-Lithuania
Have a revolution system like Mexico to focus between Lithuania and Poland and the Golden Golden Liberty, with Lithuanian infantry and plantations benefits, and Polish cavalry and farming. Have unique hussars and grenadiers, as well as tartar horse archers. They have a separate Industrial Age revolution that is a firm revolution of Russia, Austria, and Prussia, spawning associated bonuses, while having Jan Sobieski is their personality
