I havent read thru all of this thread but...
my peoblem with balance mods is that they tend to balance toward one persons playing style. One persons balance of Pangaea is to make it more like LA Ulm (armored, using more resources, more able to fight an Ulm army of equal size) while if I were ever interested in "balancing" Ulm to Pangaea Id make it less armored, less use of resources, add more stealth and give them flying units.
But Zen has done great work in the past so I will wait and see what comes from this.
