When Assassin's Creed III made its stunning debut a few months ago, Ubisoft proudly noted that they were using an actor with Native American heritage to bring new lead character Connor Kenway/Ratohnhaké:ton to life. In the game, Connor's parents were of British and Mohawk descent and the casting of a performer who himself is half-Blackfoot felt like it made sense. Getting Noah Watts also adds much-needed diversity to the talent pool of people behind-the-scenes for video games, which is never a bad thing.
Then, the publisher announced Assassin's Creed III: Liberation for the PlayStation Vita, featuring a heroine born of a white French father and black African mother. It seemed pretty reasonable to expect that the person voicing the character would follow the Noah Watts/Connor example.
