Okay, updated the poll as per requested. Some of the descriptions were too long so I had to get rid of them, but here they are in full:
Afghanistan - The Graveyard of Empires is home to a legion of Great Writers and Trade happy unique improvements.
Anangu - Aboriginal Desert Wanderers, Natural Wonders and Dreamtime focused. No Religion
Anishinaabe - Three vastly different Peoples working together for a common goal. "Council/Capital" Centric.
Ashanti - Trade Routes with Militaristic cities boosts scientific advancements. City States heed your call in times of peril. Like the Dene, lots of Drumming in this civ.
Buganda - Lake bound, African Trade civ
Cajun - Acadian Immigrants settling in the deep south. Expect Mardi Gras and crazy southern culture.
Cuba - Viva la Revolution! Very Revolutionary Centric. A very flavourful and Musical civ.
Cree - The Iron Confederacy. The profitable middleman traders whose lands spanned a continent and ruled the NA Fur Trade. A very multicultural civ with awesome benefits to reflect this.
Dahomey - Female Warriors and multitudes of Slaves. Will you continue to trade slaves or succumb to the growing international and moral pressure not to?
Iceland - A good old fashioned Viking civs focusing on Feasting, Mead, Colonization, Exploration and.... Walruses?
Koori - Coastal Aboriginal Australians. Loves to sustainably burn down forests for the sake of food. Also Kangaroos and Boomerangs!
Nigeria - Vast populous African country. Probably centered around growth in arid landscapes.
Malaysia - Primarily naval oriented civ. Stationed ships on resources boost food production and keeps those barbarous pirates at a distance. Martial Arts and Dragon guns also included.
Patagonia - Argentinian natives, the Patagonians gain bonuses from being unified in their sparseness, diversity and decentralization.
Salish - Another First Nations civ, quite the amphibious kind too. Lead by Chief Seattle. Inventors of Potluck Dinners.
South Africa - The Rainbow Nation. Gains diplomatic bonuses from domestic trade routes, and touristic bonuses from city-state trade. Led by the much revered Madiba.
United Arab Emirates - “The best things in life are free” is not a mantra the Emirati seem to live by. Lotsa faith, lotsa tourism.
Wabanaki - A First Nation civs revolving around recreation and sports. The Wabanaki invented the precursor to hockey - so expect riots, cheering and a whole lot of fun.
Zapotecs - A spooky mesoamerican civ that is primarily Faith/Science oriented. Scary Battle Priests wielding severed heads can convert distraught and wounded enemies into barbarous savages.
Zimbabwe - A defensive civ that spans the ages. Including elements up to Rhodesia, Zimbabwe has more flavor than you can poke a stick at.
