Kongo seems to be an interesting civ to play. No holy sites and being a religious convert. Mvemba a Nzinga looks strange without European influenced clothing, but I understand why they would want to depict him like this. Hopefully, he is speaking Kikongo instead of Swahili.
This seems to be part of an effort to avoid any kind of whitewashing in Civ 6. Just look at how they made Gandhi way more brown skinned than in Civ V (which is more close to reality). Pedro II on the other hand, has been 'de-whitened' since civ V, when he was more dark skinned, and now on civ 6, with black hair and bear, even though he was a plain white, dark blonde and blue eyed guy.
