Askia was completely evil back when MPMs were 5

, didn't require Monuments and Landed Elite was what is now the Tradition finisher. You could very easily get a large vertical four city empire up and running by taking two in Liberty, then running down to Legalism. It was strictly better than Napoleon's UA, with the additional UA and the helpful UU. It was Napoleon on steroids, basically.
Now Askia is great up to Emperor and struggles on Deity. Pikes > Mandekalu, and the AIs like to spam Pikes. I agree that this would be a fairly simple game if we were Mongolia. 11 Keshiks and the token Horse would wreck house.
By the way, I'm trying to figure out what is so great about Askia anyway. I don't understand why he always gets ranked so high. I'll take 6 keshiks or CKN on turn 95 over 6 Mandekalu any day of the week. With only a movement of 3 the Mandekalu can't attack without getting hurt the next turn.
You can, but you have to bait the AI into bad positions and it frequently refuses to cooperate. The result is that you don't have control the way you did with old school Horses/CC or Keshiks. The Mandekalu are unwieldy at 3 moves, you can't kill as many units per turn as you'd like, and this makes it tough to get ahead of the reproduction rate of the zombie horde.
Hopefully I'll get back to the game this evening, but I want to finish up the "new school" article on teching first. I do need to figure out what to do with all that

. Usually it's best to plow it back into units in a Domination setting (which is the only way I'll get a "Culture" win here before getting nuked to death - gimp all AIs), but I'm torn since Education is almost done and I
really want to get a University in the capital to accelerate Machinery. Crossbows behind a Mandekalu screen are probably going to be the only way to actually kill stuff on the offensive.
