OK, but are they culturally American in the game? Most of Earth's black people live in Africa, not in America (ditto for Indians, Chinese, etc). If you'd mix all those cultures in space there should be interesting consequences (both good and bad), but apparently that's too difficult and too sensitive for today's writers (that's one thing Mass Effect 1-2 did pretty well, using alien species as metaphores). A frequent annoyance of mine is when American sci-fi games try to be diverse, and all they can muster is including American blacks, American latinos, American gays, American females, basically having Americans represent all of future humanity without explanation.
