Civciv5
Grand Emperor
There wasn't a Zulu Empire,their kingdom was smaller than Belgium and they have very little achievements.Zulu ( would probably play as a generic warmonger civ like huns/mongolia, unless they can come up with a good unique stuff, which I hope they could)
If they would add another 9 civilizations, this would be my choices:
Tibet (religious, cultural civ with an advantage in mountainous and hilly terrain)
Indonesia (good civ for building large,maritime empires)
The Khmer (cultural civ that is specialized in quickly building large cities)
The Sioux (nomadic civ that has an advantage in plains)
Portugal (gold-focused civ that can quickly discover the world and build colonial empires)
The Afghans (military civ that is specialized in defending and conquering)
Kongo (civ that has a huge advantage in jungles)
Georgia (religious civ that is specialized in faith)
Poland (civ that has always happy cities)
