So, what? We make every race automatically have max level and skills and the best equipment, and be like holograms so when you turn in-game they change from white to brown to black (or black to brown to white, or brown to black to white, or brown to white to black, etc.)?
Believe it or not, you can have different skin colours in something, be it a game, a film, or anything else, without it being there to simply satisfy the overzealous political correctness crowd or to provote slavery.
So let's move on.
