I can see that this is a problem, but I still don’t think that it makes sense to say that every game has to have people of every ethnic background in it - any more than every novel should have to have main characters of every single ethnic group. I wonder if the answer may lie in more diversity among the people creating games, and especially those who get to make the creative decisions and inititiate new projects?
I’m not a historian, so if you have some good articles you can point me to on this, I’d be grateful. If not, of course I’ll google it. I do wonder if the degree of diversity varied by place, however. I’m aware that medieval Spain, for example, was extremely diverse, at least until the Reconquista. But would the same thing have been true of medieval Scandinavia?
