So after a few practice runs I got a good game going in Spain. Starting 769 I used French alliances to first take the south of Spain and by provoking rebellions and then declaring on them I quite quickly united the Iberia peninsula. This was a merc heavy strategy but I've mostly outgrown my use of them now. For some reason I didnt follow at the time the king of Italy converted to Muslim and so I have been holy warring Italy in my spare time (though plan to leave Rome under muslim control to trigger early crusades when it hits 900)
The defensive pacts against me are a bit pathetic so I will probably just keep slowly eating infidel lands. Given this was my second conclave game (first being a ragnar lothbrok run) I decided to empower my council for the vassal limit bonus and to avoid constant civil war (for some reason no matter how nice a ruler I am I get hit with a demand for higher council authority at 200% every decade or so). This gives me a large number of vassals and lets me be centralised so I'm going to shift from stewardship to diplo.
My concerns are:
A) Threat, im currently at 79%, a few more wars will make it hit 100%, are there and super bad things that happen at 100%?
B) how do I best take the south of France to link up my empire
C) What succession and laws do I want as a megablob, due to favours getting a bit out of control my feudal vassals are tax focused and my burgher vassals are levy focused so I am gonna first have to fix that.
D) What late game goals should I have? The early game was a challenge but now its getting a bit dull, I'm mostly waiting for the truce timers on italy and africa
