'Setting BB to 0 won't help sh*t in vassalizing other Muslims, if you have gone around annexing others left and right. They will hate your guts anyway.
FIRST go for diplomatic relations & vassalisation THEN you can start annexing.'
Like I said I try to play HISTORICALLY CORRECT, do the same things Ottomans did, I can give you a link if you want to read the Ottoman history between 1514-1540.....
'Why set your badboy to 0? Do you want any kind of a challenge at all? You probably play on the lowest difficultly level too right? And reset if you lose a battle? Hey, why don't you just go into the game file and make yourself some 9/9/9 military leaders or turn fog of war off?'
Difficulty Normal, Aggressiveness Normal. No reseting.
Same answer as above, its not possible, because when you annex Christian states at the same speed ottomans did, of some reason even Sunni states(which seeked protection from the ottomans IRL) will hate you, that's my problem, not the fact that other Christian states will hate me. I changed my badboy to 0 after memlukes annexation and it was the only time I did this. Like I said, if you play historically correct you have to annex memlukes(+18 happened 1517), Rhodes(+2 happened 1522), Moldavia(+2), Whallacia(+2), Hungary(+9 happened 1526) Tabriz and Baghdad(probably +5 including irak 1534), Kurdistan+Armenia(+3 happened 1514)
Now start counting that's around 18+2+2+2+9+5+3=41 in 50 years. At the same time Algeria gets vassalized(IMHO annexed is more accurate) 1533, Hedjaz is a part of the empire 1517 after the annexation of Memlukes. North Africa I part of the empire around 1551...
Now try to do this things with the current badboy value, mission impossible right? What I'm saying is that, the Sunni Moslem nation should not get effected by my badboy value, so that I can accomplish what ottomans did historically. That's why I made the badboy value 0, at least now I have a chance to this, and my badboy right now is 11.
Here is a link to a map who shows the ottoman expansion around this time:
