I'd rather that nudity just be made available in mods. I'm still a minor (for another year) and my family would most certainly not appreciate there being naked women in the game. Added to the fact that my little sister watches me play a lot and nudity is a recipe for disaster.
To put it simply, adding nudity to the game would limit Skyrim's potential market. I started the Elder Scrolls back when I was twelve with Morrowind, but I'd never of had that opportunity if nudity had been included in the game. Just remember the reaction towards the topless woman in Oblivion's game files. Bethesda doesn't cater only to advlts, and it'd be fiscally (and socially) unwise to introduce nudity into the Elder Scrolls now when modders can so easily add it and save Bethesda from any bad rep that might otherwise accompany the utilization of nudity.
Just a note: There's nudity in Daggerfall.
Also, as has been stated before, your family appreciates you breaking necks, slashing people to pieces and burning them alive, but you only go to hell if you see nipbles?
I SERIOUSLY wonder what the hell is going on wherever you live. That way of thinking usually gets people in an insane asylum (and i wish i was kidding about that). Though i guess if those "moralists" had their way they'd teach children how to fire a gun before they teach them the difference between the male and female genders.
