Seems 90s christian soccer-mom puritanism is making a comeback. I wonder how ultra violent gore action is somewhat passable but showing a bit of female skin is a no-no, US morals are funny.
Well it’s because that slippery slope that everyone says doesn’t exist actually does. Recall that the original Mortal Kombat caused all sorts of controversy when it was first released (Doom as well). Compare the relatively tame violence in MK1 to what we have now in MK11, it’s what happens when society collectively shrugs their shoulders and says “it’s just a [game|movie]”.
That nudity is still taboo in games and other media is more a reflection of no one bothering to push the envelope like they did with violence.
