Remember about 10 years ago when a lot of games censored skeletons and zombies? No exposed bone because it's really offensive to the traditional religion of the supposedly atheist Chinese.
I doubt many aboriginal people, particularly those who own a computer and will play this game, are likely to care much about their old religion. Though this does remind me of an old Native friend who was legitimately superstitious about skinwalkers, so I suppose I can't be sure.
