I am afraid it is in Spanish. My English is awful.
I think a Roman Civilization will be great in this great game.
Romans are a bit different for others civs. They can develope a unit or a discover from diferents buildings.
They can create "mitic units" that in fact are not mitic units, so they are not developed in the temple but the fortress.
Traders and Trade Ship will be ok for all the civilizations, not just the romans.
Thanks to the people who made "The Aztecs" expansion. They inspired me so much.
