What I would like to see in the mod is :
- The possibility to reunite Romania. Mihaï Viteazul did it very briefly in 1599-1600. More accurately he held the crown of the 3 Principalities of what would become Romania : Wallachia, Moldava, Transylvania. While he was himself not keen on creating a united "country of the Romanian-speakers" (Romania did not exist even as an idea by then, and Mihaï needed the support of the Magyar nobility), it could have been a way a sovereign of the 3 Principalities would have ended up justifying his power by 1700, especially in case of hostility against the Magyar nobility and Austria.
- also, the opportunity to recreate the Eastern Latin Empire would be appreciated
Finally, the completely unknown "Principality of Theodoro", which despite its Banana Republic name is in Crimea, could be in for added Lolz. It was the very last remaint of the Byzantine Empire to fall (in 1475), and not Trebizond as often thought. The cultural and military clout of Theodoro, though, was even below the one of Trebizond, so it is no wonder.
