Well I had to give up on my Mamalukian game. When Europe gets caught up in your shit you die. The ottomans were extremely successful in this game conquering most of Greece and Hungary and controlling all of modern day Turkey. Their (and my) downfall was when Castille declared on them bringing France, Castille and Lithuania into a massive war against them. Castille landed all over my coasts and although I outnumbered them, w/o westernisation I was 5 techs behind and I got defeated. Ottomans only ceded one province to Lithuania, I had to give some of my most important provinces along the coast. Ottomans decided to invite me to war against Morocco this time, they had a huge army and navy. I declined and they broke the alliance with me - That's a shame because I had been allied with them since early 1400s and joined all their wars and never signed an individual peace. But no, I don't join ONE of their wars and they break the alliance (Sounds almost bug-ish to me).
I just gave up, 1511 was the year, I owned the entire East Coast of Africa after several wars with Mutapa and Swahili. Maybe I'll try a Western nation next.
I don't get it. Why did you expand in Africa? Why not Arabia, Iraq, Persia?
