This weekend I attempted the “Rise of the Mongols” scenario for Civilization V. I wasn’t successful but I did get this achievement:
I am following this Civilization 5 Rise of the Mongols Scenario Strategy and Achievement Guide and I was able to follow it to about turn 8. I think this is something that requires practice to get. I am also trying to play it on the Deity difficulty level, the highest, and one I have never tried playing on before.
I will be trying it again, later. Though, I am considering playing at a lower difficulty.
