I'm beginning to think it's impossible to play as the Byzantines. Is there any way to survive the opening war against the Ottomans? I have tried multiple times with various strategies and end up overrun. Even though it says they only want one province, they will never negotiate for peace, no matter what I offer them. In my current game they have siezed all my provinces except Constantinople. I negotiated for military access with Serbia and pulled my troops out to keep them safe. Now I have no idea what to do except wait for the Ottomans to take Constantinople and then try again to sue for peace. Thanks.
