I'm curious as to whether or not you honestly believe it's more admirable for a game to show restraint in regards to language and nudity than it is to show restraints in regards to violence.
I love Skyrim, but I lost count of how many people I decapitated in that game. The violence in Bethesda's games is on a different level than the violence in Bioware's games; DAO is the only one that comes close in that regard(DA2 being more comical and cartoony in the way the enemies would explode).
Not to mention the easily moddable nature of Bethesda's games essentially saying, to their PC audience at least, "we're not going to include nudity, but feel free to do so, yourselves."
Only speaking for myself, and with the knowledge that Skyrim is the only Bethesda title I have played to my recollection.
Personally chose to use the Adept setting for Difficulty, as higher settings only nerfed the PC and buffed the opposition. This is not my preference for adding a challenge. So when I started modding my game, additional mods were chosen to do this while keeping PC vs NPC on relatively balanced ground. I mention this because I also choose Melee perk options to increase damage; not increase instant kills. Those chosen are generally the base five Melee Weapon Perks and the one to boost Power Attacks; skip increased chances for crits.
Also not a fan of Mod Overhauls; prefer to tailor my game more specifically. Currently have around 90 mods, but only a few are to enhance combat (eg; Balanced Magic, Deadly Dragons, High Lvl Enemies, Ultimate Combat, and Better Vampires).
As for the Nexus, I choose the option to ignore the so called Adult content mods. Out of sight; out of mind and all that.
Personally, profanity is a larger peeve than the others, as it cannot be avoided as much as the other ESRB content. I prefer to purchase games that are rated Teen to avoid such content, but prefer choice and options in some Mature titles. However, I have chosen to skip the FO series due to unavoidable language, and will stick with TES titles for Bethesda, I guess.
