I just realized from your map that 44% of civs in the Americas are colonial nations. That's a lot.
I like the european civ selection, but agreed that I'd love to see more of the rest of the map filled in. Adding in civs like the Cree and Mapuche this time I think helped fill some historically missed spots in the Americas, but I'd love to see probably one more Western Native American civ and also another eastern one, some day would love to see a Carribean one too, and yeah, certainly more SEA, Indonesia, and Africa to fill things out as well.
If I could pick the civs for a NFP2 pack, I think I would have Portugal as my only European civ, and then you could basically pick any 7 civs from the rest of the world and that would help balance things a little more.
I agree with all of this other than the Indonesia part because we already have Gitarja with Indonesia who was accidentally left out of the map here.
It seems like we have too few civs in the Americas / Africa / Central Asia given the cultural diversity. We're still eurocentric. Geographically, looking at this map, I can see three major regions of Africa that are empty, namely West Africa (take a civ like Ashanti or Ghana), the Maghreb (civs like Morocco or Berbers), and East Africa (civs like Swahili or Madagascar, or even add Oman for something else in the Arabian peninsula while also representing some of history in East Africa). In the Americas, much of the central/western parts of North America are empty - we could add civs like Tlingit or Haida for the Pacific Northwest and one or multiple of the many viable choices for other Nations like Navajo, Pueblo, Apache, Sioux, Cherokee, etc.etc. We could also probably get away with another civ in South America like Guarani or Tupi or Muisca and help skew the continent away from colonial, or include some Caribbean choices like Taino or Haiti - and though I would want the emphasis to be on new Native civs rather than ones stemming from colonialism, I'd make an exception for Haiti, which was anti-colonial in its nature. Then add one or multiple civs from Asia, including something from Central Asia. Not going to touch on that region though because I don't know enough about the choices.
So just for fun, let's say we have a second DLC pass that adds another 8 civs. Portugal seems to be one of the most requested, so let's give them a slot as the sole civ of Europe in the pass. For the Americas, let's say we get a Native American PNW civ, another from west/southwest/central NA, and possibly either a Caribbean pre- or post-colonial civ or a South American Native civ. That covers us for 4 of the 8 civs already. From Africa, let's say we get a West African civ, a Maghrebi civ, and possibly an East African civ. That's 7, leaving only one choice from Asia.
In the NFP, we're
mostly sure that we're getting Vietnam, and we'll have one more civ choice that is totally unknown as of yet. I predict that the last civ of NFP will be something from one of the regions I mentioned above or something like Iroquois. If it's something from one of the regions I mentioned, we can count that one in our account of geographical representation after NFP, essentially freeing up 2 choices instead of 1. Meaning we could have an additional civ from Asia, for example. So, in Civ 6, including NFP and one hypothetical post-NFP pass, I predict we could still see 9 civ choices: 1 Europe, 3 Americas, 3 Africa, 2 Asia. That's if a hypothetical second DLC pass has 1 Europe, 3 Americas, 3 Africa, and 1 Asia, which sounds like rather few from Asia when you look at the pass in a vacuum. I dunno. For context, if we include Vietnam, NFP has 2 Europe, 2 Americas, 1 Africa, 2 Asia, and 1 still unaccounted for.
TL;DR I think a second round of DLC adding 8 civs after NFP has the potential to get us the
geographical representation we appear to lack from a map of the civs. Whether it's enough
cultural representation is another story.
