Yes like in Fallout where it's possible to sever all limbs. The gore! The glorious gore! Also, more nudity. I may sound crass but I read books like American Gods and Game Of Thrones. So it'd be nice to get that level of violence and nudity in my video games too. The Bible has more gore and nudity than TES for crying out loud.
The Bible has more advlt content than the vast majority of mass-media products. Parts of The Bible positively portray incistual [censored], slavery, stoning people to death, slaughtering every firstborn in an entire country and the genocide of almost everyone on the planet. I can't think of a Holy Book, or mythological canon which doesn't contain such content. Facts like that are why I appreciate the Sermons of Vivec and The Real Barenziah, because the concepts presented are exactly the kinds of concepts which have fascinated cultures throughout the ages.
That being said, nudity for nudity's sake and violence for violence's sake can completely desensitise people to the underlying issues but more than that, it can become really
boring. I don't want to see a naked body every time I strip someone for their armour, it's distracting, and I'd like some of the violence in Skyrim to have a bit more of a point to it. The Witcher 2's six scene was softcoe porm and I've no interest in seeing that in a video game like Skyrim, which has other focuses. If walking in on two men having six, or stumbling over a naked woman's headless, bisected corpse led into a genuinely interesting and advlt story, then I wouldn't mind so much, but it would sure bump the rating to 18, rather than 15 here xD
