Ok, come on, GoG! Diablo 1 has a mature content warning on it, and I don't even recall 'zombie boobies' in that game..

Yet Sin! does NOT have a mature content warning, and you've got a screenshot with naked boobs right there on the product page.

Your children will see nudity and pornography. More critical is how reasonable you can be as a parent around those topics, which, you may realize, aren't universally problematic at all.
