On the OP
(btw.. "RACIAL"??? What the heck??? It's Civilization, not Warcraft).
This is directed to everyone that objected to my use of the word "race":
African. Asian. Latino. Native American. Eskimo. Norse. Mongols. Celts. Semites. Caucasian/Aryan. Etc. Those are all
races of Mankind. DNA testing can even show racial markers in EVERYONE's genes. More similar to each other than say "dogs", which come in umpty-ump breeds that don't look much like each other beyond having four legs, a head, and a tail. As it happened in History, many races _also_ established empires under their own names. But as it happened, many races splintered into multiple empires. (E.g. Asian split into Chinese, Laotian, Korean, Vietnamese, Cambodian, etc.)
Since the game speculates on ONE nomadic tribe that grows and expands across six millenia, it is likely that its origin would breed a distinctly unique -- but still Human race. Over time, there would undoubtedly be extensive intermingling with other races. But there at the beginning, "race" definitely applies.
Seeing as you're new to Civ: there are no 'races' in Civilization.
Just as a clarification, I have played EVERY version of Civ going back to Civ 1. I also, incidentally, have played all of the Civilization board games (both Trefoil and Avalon Hill editions) that inspired Sid to make Civ in the first place. So I am familiar with EVERYTHING that has come before Civ6. So it bewilders me that with EVERY new release, Firaxis effectively takes "three steps back" by dumping numerous successful features from those earlier versions. Unless, of course, it is a matter that Firaxis is entirely cognizant of what they are doing by initial releasing only 60% of what they manifestly
could be putting in the package, but are deliberately setting aside to spoon feed us in the form of DLCs and expansions. (Would Firaxis be so pointedly mercenary about the way they Market their products? They are, after all, a
business, and businesses exist to maximize Profits every way they can.)
