I Hope CA will depict correctly de cities-fortresses of the celtic-germanic tribes...however i have no hope they refllect the castro culture of the iberian peninsula, but it would be quite realistic to make an "generic"style of settlement for the peoples of western europe based on the famous murus gallicus, instead a Asterix and Obelix village like in Rome I...I think it would be easy to make the things correctly, acording to the CA lazyness...I was just furious when in Napoleon, the egypt campaing, there was western buildins in egyptian cities

P.D. sorry for my bad english
