While I disagree with your tone (kinda snarky there mister
) you are 100% correct. Hell Duke Nukem is gonna be M, GTA is M, Fallout, Fable, and all these other things are M. Common elements? Violence (on graphic levels for some), nudity, sixual themes (Duke get's strippers, GTA, Fable, Fallout, etc. has prosttutes).
Leisure Suit Larry has a damn M rating, so does Postal 2. You are constantly looking for six in one and in the other you get to light people on fire, pee on them to put it out, then come back with gonorrhea and light them on fire with your urine.
Edit: Forgot to make my point. This is not a big deal, especially not for an M game. If you live in some country where this kind of pathetically tiny and inoffensive thing get's banned than I feel bad for you but at the end of the day I'd rather you suffer without Skyrim for me to have a better experience in my copy. Maybe I'm just a dike though.
