Assassins Creed 2 is a great game for children 13 and up. But that is only if they are mature enough to handle it. Violence: first of all, you can turn off the blood, so the only blood you can see is in one cut scene when a man is killed. Though there are some violent acts that play out durring the course of the Game, there are however much more violent and "disturbing" games. Games such as Dead Space and Fallout 3 both have gore (e.g. limbs being shot or blown off, or decapitation). Assassins Creed 2 has no gore at all. in Assassins Creed 2, when somebody is stabbed there is a small spurt of blood that comes out of where the charactor was stabbed and they fall to the ground. There are many more violent games out there so this isnt all too bad as far as violence goes. Language: The language in Assassins creed 2 isnt very light. swears such as F*ck ans S*it can be heard in the dialogue but not too often. There are also some swears that are spoken in Italian. But is language is a problem, you can turn down the voice volume in the options and turn off sub title so you can hear the swears. (unless you can lip read lol) Plot: The plot isnt the easiest to explain. You are a man in present day who is put into a machine that can let you re-live the lives of your ancestors. you are a decendant of a long line of assassins and when you go into the machince, thats when the game starts. you then take on the role of Enzio, a man who becomes an assassin so he can kill those who have wronged him and his family. Sexual content: This is a big deal with parents. when they see "sexual content" on the back of the box. Well lets get this out of the way, there is NO nudity. The Most graphic scene of sex is when at the very begining of the game when you start to play as Enzio. Enzio and his girlfriend are kissing and they get on their bed and then Enzio puts out the candle in the room and the screen goes black. Infering that they had sex. There is no Nudity at all aside from some cleavage you can see from women walking on the streets. All in all I think this is a GREAT game for you child, and it is one of the best games of the year in my opinion. The violence can be bad but can be toned down. The language is somewhat crude, but you can mute the dialogue and turn off sub titles. The sexual content isnt at all bad. So if you have a Mature child (probably best suited for Mature 12 and 13 year olds.) that can handle some mature content. I think this is a great game that they should experience.
