I don’t think one hispanic character in San Andreas dismisses the theory of less hispanics in games. I saw that article as a positive step in making gamers/gamemakers to avoid racial stereotyping and that their audience is a global one. It’s funny how is hard to think of gaming main characters who aren’t white, straight and for the most part male.
As for irish accents in movies, it isn’t really on topic, but the more we make ourselves, the more the world will be used to it. And that applies to everything.
