Me?
If so 18 million restarts... For once that's not really that much of an exaggeration, Austria, Poland to rival Ottomans but not rival each other, Poland to get the PU.
I waited for Ottomans to declare on Byz, they hit the Byz forces and chased the shattered army into Morea. Declared on Byz, sat 1 troop on Constantinople allowed Ottomans to siege through me. Already had troops waiting on ships to cover off on all the rest of Byz/Athens land. Ottomans fought the war, I took the land.
Only at that point, with a diplo rep advisor, 'threatened' by the Ottomans and built upto 5 over force limit could I get an alliance with both Poland and Austria.
From there fabricated on Candar, the 2 province purple guy on the north coast of Anatolia, took him out fairly easily but it allowed me to breach the next sea tile and fabricate on Georgia.
That's where my game turned, peaced out for 7 provinces of Georgian land with no coalition forming. From there consolidated my position in the Caucuses, Shirvan, Gazikumukh, Circassia, Crimea, waited for shadow kingdom and sniped the Genoa provinces in the area too.
For reference, the mountains of the Caucuses are an amazing strategically defensive position, throw a fort up in Abkhazia or Mingrelia both mountain provinces and you can chew through the Ottoman manpower pool with relative ease.
After that ate my way through what was left of Quara, Taberestan into the Persians making sure every fight with the Ottoman was a defensive one, a fight where I avoided contact as much as I could, fleeing north past the Caususes whilst Austrian/Polish forces headed for Edirne. Once Edirne had been taken my 30 odd mothballed gallies along with my trade ships were ready to block the straight. Even if allies pushed into Anatolia and got smashed they'd have somewhere relatively safe to retreat to. It helped that the Ottomans had eaten all the way upto Austria and half of Hungary at this point, plenty of forts for war score.
3 Defensive wars later the Ottomans were done really, the main threat turned to be Russia. By then I was strong enough for offensive wars with the help of a newly formed Commonwealth.
Game ended with me just trying to cut my way into Vijaynagar, but with no client state/vassal feeding going on I couldn't really take that much each war.
Looks impressive, and it's a lot of land but they're big, empty provinces.
TL DR; Eat around the Ottoman.
PS: Knights can raid, its boarderline OP in the beginning...
