I'm not a big warmonger either I just like that Shaka offers a more interesting domination that common Civ. Same goes for Genghis KhanWhy? You like dominating other Civs? You're a genocidal player....
I hate the colors (why green? why not reuse the Civ5 colors?), the music is too Westernized (Lion King type music), Shaka will always hate me in-game (I never bother to form Corps and Armies, and I can still destroy the AI's Corps and Armies easily). This is a Civ I will try to do one domination game in and never play again. Sorry, I'm a pacifist at heart.
Oh, and his voice actor is worst than his Civ5 one. He sounds too friendly.
And the Zulus better not be the last Sub-Saharan African Civ, Firaxis. At least give us Ethiopia and Mali later.
Also, doesn't Nubia already use Zulu colours already?
