At least for the PC players, the potential of an M. Console realities may hinder that, as would a surge of puritanical guano (although since DNF has been picked up by another game co and will be released in 2011, there may be a lot that gets missed in the uproar over the Politically Incorrect One....
), but war is not pretty. And simply following archetypes means that the elves, one and all , are pretty agressively nudist in social settngs, compared to humans. If dragons go on a tear through the game world, there is no child friendly way to burn to death. People sleep nvde. Swim nvde (Skyrim's Polar Bear club! Although seeing a bunch of hairy Viking anologues....and that just the womenfolk....might damage some.....). Worship deities and cast ritual magic spells sans wardrobe. Now the environment might mitigate against it being in any way shape or form =common=, but the idea is not to have Leisure Suit Larry meets Drunken SCA tourney. But to have a world that flows. Agressively amputating anything that might have sixual or violent overtones can be just as jarring as reaching the end of a dungeon only to find Auriel breakdancing au le naturale singing Inna godda davida in helium falsetto (although in -some- dungeons, it would have made the trip worth it).
Of course being within a year of going gold, if it ain't there now, it ain't gonna be.
