My most recent game, a Croatia run. I did not start as Ragusa though, but I would like to give that a try some time. Instead I released from Hungary, declared independence, went forward from there.
Commonwealth was a monster that stretched from Brandenburg and Silesia all the way east into Yugra (so beyond the Urals), and at one time even stretched south into Slovakia as well as the land between the Caspian and Aral seas. Muscovy died very early to a triple combo of Denmark, the Commonwealth, and Perm.
I wish my borders looked a little neater at the edges but things didn't go as I planned.
Had fun with diplo-vassalizing this game, I usually don't rely on it. But in this game I managed to conserve admin points by eating up well-fed vassalized Serbia, Byzantium, Mentese, Syria, Iraq, and Mamluks.
