Are there even any charges? If this is true, then it is so stupid that I can't come up with any kind of metaphor to accurately convey how stupid I think it is. Dear god. This is much worse than the Resident Evil 5 controversy. That was completely legitimate compared to this.
Seriously. At least there we have a historical context of Africans being depicted as animalistic savages by European and American writers over the last couple of centuries. At least there you can look at screenshots of the game and say "gee, this reminds me of the horrible racist shit people were making two hundred years ago" without it being completely absurd.
Even if you disagree with that assessment (and for the record, I do), there is a valid argument to be made for it. You can weigh the sides, listen to the people involved, compare it to other works, etc. This is just dumb. China has their Jack Thompsons too, I guess.
