The Lakota are included because they appear to encompass all of the plains indians including the Souix. I think that the Hurons would be just as good, but what I don't think people realise that there is to my knowledge no historical background to the Enkidu Warrior, so why it is the Sumerian UU for Civ? I have no idea, but Brian Reynolds will not steal a "made up" unit. I think one of the leader names for the Sumerians would be; Sargon of Agade, who was the first empire buider, he ruled from Akkad(where Babylon was, or was to be) and counquered much of the Fertil crescent. I find it odd that the turks are in the game and the Arabs are not. But I think that all of the civilizations named deserve to be in an expansion, RoN does not seem that hard to play test, and the civ traits for most of the civs mentioned should be stright forward. Vikings would get good lightships, and maybe their unique unit would be have a faster transport form, The Poles would have to have some kind of UU cavalry line, Hussars ect. Arabs could have good light infantry and cavalry(Maybe shared stuff like the persians have with India, so the Egyptians and Arabs would have "Shared" UUs). Vikings I think you would give an assimilation bonus, or some sort of expansion bonus, along with some sort of naval or military bonus, Arabs would get Technology and Temple bonus,' aswell as culture, Poland could have more productive mines and/or farms, I think that Austria-Hungary would be a good Civ, as would something like Ancient Ghana, Sangia or benin, another African civ along with the Arabs would allow more territories in the middle-east and africa, I don't know what I would give the austrians, a productive or culture bonus, I am not sure. Purtogal is a great idea, not as but almost as influential as the Spanish, they could have better heavy Ships, all their ships could fire farther(maybe) and see farther. They would have a wealth benifit, or something to that affect, and I would give them better Classical-Gunpowderinfantry of some type. You could have their scouts be able to go into transport mode without a dock having to be build, plenty of possibilities. UU and traits for Sumeria, or a South East Asain or Pacific Islander people could be hard, but it would be cool to see an aborginial or polynesian civ in a non-mod game for once. Any Ideas for traits for Khymer, Sumeria, Thialand, the Viets or Burmese?
