I had stone close to the capital, and founded a city next to it. Here I built the great wall, while in the capital, I built the pyramids, after another settler was done. I stole some workers from Mansa Musa and Joao, and pillaged some of their improvements with a woodsman II warrior.
I teched first to mathematics, taking only masonry and bronze working ( discovered copper) from the lower half of the tech tree. After maths, I chopped two forests to finish the pyramids, after the great wall was completed for some turns in 2nd city.
To get the Engineer, I continued with Aqueduct > Hanging gardens in the capital. Meanwhile I had made peace with Mansa and Joao, and founded another city. Two Barbarian cities were build closeby, on good spots, and I took them with Axemen.
Now I had alphabet, and was starting stealing, and trading techs. I traded away only techs that most AIs had, keeping my monopoly techs to myself. Mansa cut of the direct (neutral) route to Joao, but fortunately, Joao took a Barbarian city to my southwest, between me and Saladin.
I teched further by researching currency and code of laws, founding Confusianism. However, I've adopted Mansa Musa's Buddhism for long, sine it spread in most of my cities, and also Shaka and Joao are Buddhist. I was first to get Metal Casting, and built the Colossus in the capital, which took only 9 epic turns with copper.
I got Iron Working +

by trade for mathematics with Saladin (no Iron discovered in my lands), when all other AIs had maths already. Saladin is very low on the scores, so I try to keep him competitive, even if he's Hindu, I am not affraid of war with any of my Buddhist brethren, since I have the Great Wall, walls in my cities, and soon castles, and yes, even the Chicken Itza (for small chance on Confucian shrine).
I stole most of the religious techs now. while researching machinery. I could steal construction from Shaka, but all my spies are caught the moment they enter Zululand. So after I had machinery, I had to trade for construction. The great engineer that I got in the capital was saved to bulb ~1600/2100 beakers of Engineering, five turns left to research it in ~500AD.
I built castles and in all my eight cities, I had also courthouses in all. Now I set my espionage to 80% for a while, directing the EPs towards Joao, Mansa, Shaka, and Saladin. 2:2:1:1. I was just stealing techs clockwise, while researching calendar (built maussoleum) and then the Optics path.
Shaka wanted my head on the Impi stick, so he declared war. I defeated his stack of horse archers, swordsmen, impis, and axemen at the loss of one axeman. The I razed one of his cities, and took another one, not to upset him for razing more cities, in the hope of returning it after his capitulation. But he didn't want to capitulate so far. War weariness started, and that citiy became hard to defend, so I made peace. I will continue the Zulu campaign later, when I get more macemen (stole civil service from Joao), and Theology from Mansa Musa.
