I think that is a good idea. As soon as I come up with ideas I'll post them here. Rigth now I can't think of anything, I should playtest some more. Currently, Romans are up. Things are going pretty well, this time I went for the Greek independent cities first, and ferried a second wave of Legionairs to Egypt who quickly took over Cyrene, Alexandria and Diospolis.
Workers costs are getting slightly out of hand though. They are expensive, but they can be stolen from other civs or independents. It is weird though that they cost more than a settler. Especially compared to for example a Legionair their cost seem somewhat off. It is more profitable to build a stack of Legionairs, attack a random civ Scouting for girls workers and take some cities on the way which you have to do anyway.
