People are calling Black Ops 2 the game of the year

I really don’t understand what it is about, you just go out on streets and kill people hijack their cars .The worst thing its played teenagers and kids who are 10-12 years old. There is nothing educational in that, well you only learn about guns and pistols, which is bad because you are learning about things that can kill or create mass destruction. It also has a very bad impact on small kids when they watch their brothers or sisters play Black Ops, they make the character a role model and if the character is fighting they too will learn to fight for everything and never to problem solve. I also heard that they deal with drugs and smoking in the game so the kids who are playing the game might think that taking drugs or smoking is right (which is a wrong). This is why I think Black Ops should be played by adults not teenagers or kids who are 10-12 years old.
