Mamluks AAR
Upon starting the game, I realized that I could vassalize Candar peacefully, so I did. Upon completing that, I declared war on Karaman (who annexed Ramazan), as well as Dulkadir, to vassalize them both.
During this war, Toma (Tunis), allied to the Ottomans, declared war upon me. I peaced out Karaman quickly for a province, and decided to leave Dulkadir around to have access through them.
I was able to fend off the first big battle of combined Ottoman and Tunisian troops, and blocked the way for more off by sending my galleys into the straits between Greece and Turkey. In the meantime, Fitz (Timurids), who had been at war with Qara Qoyunlu, took their Southern provinces and released Iraq/Syria, in order to box me out of expanding into the South East.
My goal was to get the Ottomans out of the war as soon as possible, then beat Toma on his own. Sadly, despite his reassurances that he would not help Toma (or fanboi's Ethiopia) fight against me, Fitz allied Toma, got called into the war and landed troops into my land. There was no way for me to win this war now - against the combined troops of Ottomans, Timurids and Tunis.
I decided to drop out of the game. There is no reason for me to keep on playing, as I'm sure Toma and Fitz would've demanded the lands that allowed me to expand into the Ottomans' territory. This would've resulted in being not able to expand towards the West, the East, the South (with fanboi there) or the North. And even if not, I'd just become their whipping boy. There is nothing to do for me but get slowly nibbled to death by Toma, Fitz and fanboi. And since that is boring, I'd rather sit out this session.
Morale of the story: Don't even attempt playing if 2-3 players are surrounding you. I should have surrendered and given up playing the moment Fitz had picked the Timurids.
