I've noticed that everyone except the soldiers are wearing togas and Greek tunics in Celtic towns. Shouldn't the men be wearing just trousers or a Celtic patterned tunic over trousers while the females wear Celtic patterned tunics? If there can be a variation between Roman togas and Greek tunics then there should be one with Celtic clothing as well.
On that note: why are all the Celtic units using historically inaccurate shields? They should be using what the Greeks called thureos. This is a lesser problem though.
