I'm not sure about the Income Variables section Colovion - there is a lot to consider in there. However, I do like the Food/Watchtower ideas. It adds to the variables of war and opens up more possibilities - a "scavanger" unit trait comes to mind, i.e. a unit that can live off the land without logistical support. Giving watchtowers more importance is good too. There is some good potential in this seedling Colovion - or at least it seems that way.
