Why is assassins creed brotherhood an 18

There is quite a lot of gratuitous violence, adult themes, profanity, but mostly because it's a game based on your assassination efficiency. Isn't it enough to keep kids from finding driving a blade through the back of someone's neck silently a cool thing to try?

I don't want to sound like a prude saying that though. My 13 year-old loves to pull up a chair and judge my assassination skills as I perform them. I don't mind his input, I just like having his involvement and enjoy watching his excitement when I slay 4 guards in under 3 seconds before anyone notices. He especially likes the crude Italian taunting I lay on my foes. Fortunately, he is a good kid and if there was a game which he cannot play based on the rating, he will ask me to play and ask if he could watch.

Ehem... bad, bad game. Just terrible. Aught to be banned...

Personally i disagree, it is not an 18, it's a 16. And there is no neck slicing, i believe either pegi or the german equivalent rated it 18. I think it is fine, shouldn't be banned. You kill bad people, quite contrary to the term assassin. It's a great game and there is no "bad" graphic violence, I'd let a ten year old play, really. And the puzzles stimulate the kid's blade during the massacres.
