Hey Wolf, great job so far! Just two suggestions because I'm ultra-picky:
1) About civ names... there're several civs/regions that went by different names depending on time, namely the English/British, Romans/Italians, Ottomans/Turks, Russians/Soviets, and Persians/Iranians. I'm under the impression that the designers chose to use the name that the civilization was most prosperous under (and of course, the Romans, Russians, and Persians are no-brainers), which would also justify making the Turks the Ottoman Empire instead of the Turkish Empire (which it was also called -- and which I think is a better general name for the civ). But what really bugs me is that the Brits go under the name English Empire, when their centuries of empire and legacy was as (and continues to be) the British Empire. I know it sounds silly, and anyone could probably change their xml easily, but it feels weird having all these ships running around as the English instead of the British.
2) I believe this was mentioned earlier, but I guess it was looked over 'cause most of the mod focuses on European civs... but the other thing that bugged me -- and I'm sure it bugs other people too -- is the "Native American Empire." Ideally, it'd be neat if you could split it into the Sioux/Lakota and Iroquois, but I'm more specifically requesting the former. After all, the wars with the Lakota (Battle of Little Bighorn, etc) were during the late 19th century, within the timeframe of your mod. The game already has Sitting Bull, so I guess it'd take a
different flag and some other changes (city list) to make em real. I was thinking it would be cool if Civ had Sioux that played like their RTS (Rise of Nations, AoE3) counterparts with their cavalry-focused, nomadic style (no food/population generation, borderless buildings). So maybe they could have a UB like a stable that reduces maintenance costs, or a courthouse (tribal council) that adds experience points to mounted units. As for their UU, it'd have to be some mounted rifleman that replaces the cavalry. That would be friggin awesome instead of the "Native American" bs we have right now.
Anyways, keep up the good work!
