you said that the germans and sarmatae were the least civilized of all the barbarian factions. What about the casse? I can see how the iberian tribes were influenced by carthage and greek colonies, gaulic tribes by rome, greek colonies, and dacia by Greece, but what kind of knowledge would the casse have acquired and from where?
I guess to better restate that question: When you say a civ is the least civilized, how are you comparing it to the other civs? Sanitation, road systems, education?
