Here's a guide on how to change unit flags:http://forums.civfanatics.com/showthread.php?t=390101
I would complete AMCs with a total of ten civs (who is the 10th civ is still to decide). After that, I'll do just a single civ (I don't want to reveal its name - I just say that it's a abstract civ, which, incredible to believe, the hardest thing is to name it, because it never existed - I just want to make playable its leader, which was a real leader instead)
I guess that your mod is the unique that makes leaders screens
I don't agree with Civ'ed, there are other points to correct besidefallenfell.
These are : "your people look toward you" and "to keep on supplying them with".
Also, when you add the Scythians, why don't you make the Kurgan the UB?
