I like the idea of a civ that specialises in a dark age. It would be a better way to show how a dark age / heroic age cycle could be a prefferable route to just chasing golden ages all the time. Byzantines would also be very appropriate as they were the prominent superpower in the historical dark ages. Maybe a bonus to force other neighbouring civs into dark ages would be good, or something to do with open border bonuses as historically they played a prominent role in granting passage for numerous crusades. I love the art style for this civ they are not quite European and not quite middle eastern but something in between. It would be great to represent this in the unit/ city design and music. I would also love to see Greek fire and the Varangian guard. Anyone remember how good they were in Medieval 2 Total War? It's also funny to see how designs for Byzantines and Ottomans have intensified as we now realise we are not getting them in the R&F expansion. I suppose its a healthier way to respond rather than just ranting our frustration on the forums.
