So, once survival is established, what's a good next move?
I've just had some very good luck on my third run - venice got into a war with austria and aragon and I was able to take their fleet out, netting me naxos and crete - still during my first ottoman war. Rebels popped and I took all the ottoman's greek provinces. Then bosnia reduced serbia to an OPM, so I diplovassalised serbia, attacked bosnia for those cores back and force vassaled both them and wallacia. All this before 1462! Unfortunately, I'm almost out of manpower.
So, the ottomans have no troops on the european side - a dow for bulgaria will be easy with blockading. But Candar has trebizond - I can probably take them, get trebizond, then hopefully diplovassalise OPM georgia and release it from AQ. Is this a better option than taking asia minor? My last playthrough I took asia minor fairly early, but got bogged down with rebels as I couldn't convert it.
Problem is I'd rather go for innovative than religious. Does anyone have any good expansion plans for an innovative byzantium or is religious necessary? Long term goal is to reform Alexander + Justinian's empire.
