The scene that got Larian banned is the bear on vampire romance and most people assume it was banned as so kind of stand against bestiality or gayness but it was banded because they hacked the clothes of the druid in his human form i.e he was nude because Larian removed their own filter
China and Japan have very different laws regarding nudity and sexual content. Also, where Japan is bit more liberating on what sexual content allowed for public, censor for genitals is an absolute requirement regardless on what kind of content actually is. Failure to provide one generaly means game will be banned.
