In the grand scheme of things, what difference does it make whether a generic main character's skin is white, brown, black, yellow, green, etc or are male or female? Diversity for diversity's sake isn't a huge deal until you want to gender swap or race swap an established character just because, I mean what does that really accomplish?
I have no issue with a more diverse cast in games but I believe storytelling and gameplay are far more important than racial diversity or lack thereof imo. Plus if skin color or gender are deal breakers for some, than they should stick to playing games where you can create your own character like Skyrim and Minecraft.
