Yeah, for DE I'd like to add a Coin resource, which is the resource you trade with and buy resources with, and is what I was basically advocating for H:C but with Rupees. Coin would be used to hire mercenaries and stuff like that and represent money or currency. Yes, they had advanced coinage in the 0 A.D. time frame.
Problem is maintaining component files that will constantly be deprecated. So, I refuse to add stuff like that until Beta is reached.
