Started Yemeni briefly. First thing I noticed: the trade will be harder than with the Omani. No one likes me. But that's not bad. Second: the accumulated culture actually decreases in the capital early, before I built some more cultural buildings. I even dropped below 15 threshold for a free specialist. That's probably caused by the strong Arab culture from Mecca, maybe the Emperor level makes it harder too. Third (the real problem, will try again later): Mamluks declared war to me immediately after their spawn! Why me, why not Arabs? I didn't even see Mamluks. They had open borders with Arabs and evil Mamluk guys came to my capital for no reason Time to bed.
