No actually, I did it on my own mostly, even though I had help from Wallachia and Hungary early on, but Asia Minor was just me, going patiently from country to country, closing the Ottomans in and basically finishing the job. Yeah, it wasn't all that easy, but I played on Normal so I don't know if that accounts for anything. I mainly followed the advice people gave me, build the fleet, close the channel, win.
No, I am not using any mod, I looked up how to change the country name on the forums and put the name in. I saw that was how the Greeks called the Easter Roman Empire and I said "well, since I'm already giving Greek(ish) names to provinces, why not do it for the whole country?"
And thanks for the welcome
