None at all, it was tempting at times though.. Took 3-4 restarts to get the game off the ground.
Did use a gamey exploit, however, kept releasing vassal candar/karaman (lowers BB by 2 points/province), later to cancel them as vassals only to reabsorb them using the reconquest CB for no infamy gain..
I was lucky enough to get the Mamluks into a Personal union in 1405 as well, saving a fair bit of trouble.. never inherited though, just integrated in the 1650s :/
Main trick was to maintain naval supremacy in the Mediterranean allowing for quick shuffling of troops back and forth to cover all territory, galleys and transports are really cheap to maintain even when far above the support limit.. This allowed for 40-60k troops to make landfall in portugal/castille while still maintaining the capability to rush back to anatolia in case of rebellions. Avoided angering England and built up 50 galleys to deal with the Portugese and Castillian navies.
Hordes were menacing in the start, both the golden horde and the Timurids were satisfied with a concession of defeat to go away most of the times though..
Naples/Sicily were the first to be removed, followed by Portugal and (partially) Castille. France was scorched earth to kingdom come and forced to release the major states (Guyenne, Dauphine etc.. the war took a good 7 years though). With France nullified, remaining Castille and Aragon were absorbed. This followed a verrrrrry long european war to dismantle the HRE (stability took a good 3 years to regain at this point making 'A Formal Request' not to be toyed with)..
Though any war after this was far from trivial (quite large Austria and Bohemia), it just sortof rolled onwards.. Added trade, tax and production income lowered stability costs to about 8 months investment per step by the time i moved the capital and swapped culture and at that point it was just about waiting for the required cores to fire..
Germany formed in mid 1677, kept playing a bit but decided to call it quits, achieved what I set out to achieve
