It comes down to the golden rule. Treat others as you wish to be treated.
I have no problem with characters being whatever the developers want them to be. Whether that be a minority action hero, a bald white space marine, or a half naked warrior princess. Its their game and their vision after all.
That doesn't mean we can't be critical of design, or concept, and yes that includes the race and sexual orientation of the character. That said, the discussion around this should remain civil and not turn into a "witch hunt", or some sort of outrage where we try and get an artist fired or developer blacklisted. That is the stuff I would love to see stopped.
In my view a black woman in a Tankini is as valid a character design as Kratos. We can debate the decision to show skin or not till the cows come home, but in the end it is art, decided on by the developer.
I guess what I am getting at, is I would love to see discussion here remain friendly. For example, some people think characters like Cammy are cool, and hot, and powerful, others think she is objectification. Thats perfectly fine, but we need to learn to agree to disagree and not demonize each other.
