Speaking of later-Age nomadic/pastoral Civs, I just finished reading William Taylor's new book, Hoof Beats: How Horses Shaped Human History, and on this particular point, they had assumed that Native Americans didn't get their hands on apperciable numbers of horses unntil the early 18th century. Now, from archeological finds of horse remains all the way up to Wyoming, it seems that horses got loose from Spanish colonies in Mexico and New Mexico a century earlier, and within a half-century had spread as both domestic to the natives and feral horses all the way north across the great plains.you also get potential for ppl like aboriginal australian cultures, which don’t allow their dead to be depicted and the pueblo, who hold the speech of their language to be of religious importance and therefore a closed practice.
not to mention the flexibility in settlement type makes nomadic peoples or people with semi-mobile settlements or extremely small settlements make WAYY more sense. an exploration era inuit would be significantly more viable in civ 7
Which means that all the Native American groups famous as 'horse people' - and pastoral nomads - were that way from the very beginning of the Civ VII Modern Age around 1600 - 1700 CE and so a Lakota/Souix, Commanche, or Nez Perce Civ could be represented with all their famous attributes without fudging the dates or any transition required.
But for proto-historical civs like Minoa, Etruscans, Xiongnu, and so forth, I'm quite on board. I'm already delighted with how civ switching and detached leaders have enabled us to include the Mississippians (though, granted, they did have both leader and language options--e.g., Tuskaloosa speaking Choctaw would have been fine--but are definitely easier without).
