Playing a game as the Umayyads. The balance between them and Léon seems about right if you're representing the combined power of the Kingdom of Léon and the County of Barcelona. Although, Léon has a stronger starting force than the Caliphate, which doesn't seem right for 1000AD which was more or less the peak of Andalusian power. (at least, until the chaos and civil war between about 1010 and 1030)
Yeah, I know this isn't really historically correct, but actually I wanted the AI to conquer the Umayyads eventually ... which however never happened in any of my games ... but I'll try to fix this problem in the next version, though I'mnot quite sure how to manage this.
Over time the Caliphate's culture pushes Léon's back.
It's about 1350 and I've conquered Léon and France, just started attacking Holy Rome now but lost most of my camel archers at the walls of Milan.
2 bugs:
Mecca doesn't seem to be the Islamic Holy City (there is none).
I started with three light cavalry units in the Mongolian stack in Central Asia.
Yes, I know these bugs, but having only very litte time, I forgot to fix them yet.
