I don't mind but you have to tell me how to do it... er... maybe I just enter the World Builder, save it, and then load it as a scenario? Do I also have to add techs to the Barbs or anything fancy like that?
EDIT: I tried to do what I said but the AIs seem to start with Immortal-level units... do Deity-level units have to be added in manually? Is there an easier automatic way? If there isn't an easier way, how many units does each AI need to get added to them? Do special scripts need to be assigned?
