In Dragon age. roughly 50% of all random NPCs are black. By which i mean "African american" (rather than african) This is not explained in any way. There is no migration wave from anohter country, theres no ethnic group that has a distinct name, or another way of speaking. They are just simply the same people who live in a place that looks like its a Pastiche of Iceland and Englnad (Ferelden specifically) who are, for no reason, Black.
You're missing the point of the image @_vic_ posted. This only seems jarring because it conflicts with your politics. If it didn't you wouldn't notice. It only seems political when it clashes with your politics. If you counted 50% black, how many redheads did you count? How many people with green eyes? The creators of the game had vision of a world where the color of one's skin is no different from the color of one's hair or eyes.
And for some reason that seems jarring. It seems very salient to you whereas it doesn't to me. And the reason it doesn't seem salient to me is explained by one of your other comments, that the people in the Witcher look Slavic. But Americans like me don't see that: slavs, aryans, nordics, italians, celts and alpines all look 'white' . We've lost our ability to make the distinctions that seem so important to parts of the European right. (although I've spent enough time reading right wing accounts of race to know those names and can, unfortunately, see what they see) So the idea of a world where these sort of distinctions don't matter and don't need to be explained doesn't seem so fantastic and/or jarring.
Similarly, I think you might not realize when right wing assumptions make into games and other forms of fantasy. When I read Heinlein I'm listening to a lecture on the virtues of free market capitalism. When I read Larry Niven I'm getting schooled in utility maximization. The point of Alan More's The Watchmen was to let left wingers like me realize that their form of escapism is proto fascist. What kind of person decides to put on a hood and hang criminals? What are we saying when we create a fantasy world where the uber wealthy, the Tony Starks and Bruce Waynes, decide to use their money to save the world? And eugenics? Wow. Video games are the place where eugenics and related theories of genetic determinism thrive. I'm stronger, smarter and wiser than anyone else because of gifts my father passed along to me? I was just born better than others? If I had a child with another Bhallspawn would those powers be magnified. And Nethril? The creator of that setting has said in no uncertain terms that the setting is a reflection of his fundamentalist christian worldview. Same with Dragonlance -- one of the co creators wanted to convey an evangelical message, spread the good word: the gods are coming back.
TL;DR -- politics are everywhere in video games, your politics determine whether you see that and what you see.
