Work has started planning units and governments to be added. As soon as that is done the mod is going to need someone who can make unit pictures and someone to do the Civilopedia. Also we may want someone with a good knowlage of history to help on that bit. So far the tech tree up to the first techs requiring prerequests are done. Much of the tech tree up to the industrial age will be very much the same.
The first new unit planned is called the supply cart and it will allow you to add to population of cities by using production instead of food or costing the population of other cities. More information will be avalible on the site soon.
