That's why I didn't go any higher than 3 (and then only for some provinces like Bulgaria, Estonia, Prussia, and a couple of others).

I have some more questions. I've made a seperate copy of the XL Early Startpos file and I'm trying to create a campaign that reflects Europe as it was in 1025. I want to change the names of some of the factions (specifically, I want to change the Armenians to the Chazars and the Volga-Bulgarians to the Pechenegs) and it would be nice to change some of the unit names as well. I'm completely new to modding. How do I do this?
