(btw just to precise .. i'm not American... I live in Quebec, Canada) :)
The American culture is indeed dominant like Kasz216 said and Japan was also influenced by that culture. We are all influenced by it.
There's still some games that have black protagonists (can only think of black people atm.. sry no offence to the others) there's Need for speed series, GTA (look at the hero of GTA VI) I see many games that it's genre is oriented toward hip hop & rap music with their dance style and fashion. This is from the afro-american culture. :) It's everywhere.. not just in games. :)
The world is Square.
