everything done (except the "lowers faction standings" and the kill all living units. Will do the faction thing soon. Not sure about killing all living units. What about Heroes? If you loose them, why switch to a different civ?). Flavorscreens done (they are python). Which preferences should the Civ have in Flavourstarts? (Bonus, terrain, features, etc.) For Improvements you need to make a new artstyle, yes.
