There was a great article put out by a Magic: The Gathering designer named Mark Rosewater yesterday. In the article he lays out some reasons why games designers should design their products with diversity in mind. Basically, the more people that can find themselves somehow reflected in your game, the more people will like your game. From a purely business standpoint, it's ridiculous at this point to design a game that doesn't show a full spectrum of character diversity. Rosewater mentions that Magic now has its first major trans character in the game and what a postive reception that character has had. He also states that Wizards of the Coast ensures that they have an equal representation of the sexes of the characters in their cards. Nicely done! I'm not a Magic player myself, and thus did not know that.
I couldn't be happier than to see the game industry finally coming around to this viewpoint. It's happening just in time for my own children to be entering their teenage years. Thankfully, they won't have to put up with playing games where all the heroes are white males and any women included are portrayed ludicrously rather than heroically.
Gaming is currently undergoing an upheaval in terms of how it is working to expand its customer demographics. People from all walks of life have discovered that games are actually fun to play beyond childhood. In order to keep those people in the gaming community once they enter, gaming products must welcome them in by reflecting back to them those qualities that make them special as people.
