Common Sense says 15+. What. The. Heck. This game has been censored SO MUCH, that I think I would let my 3 year old little cousin play it. I really do. There is some spicy language such as whore, masturbation, sex, and some other stuff, and references to drugs, but we all know that that crap will go over kids heads. Green Day is one of the most influential and thought provoking bands of us kids' time, and while I put on for 10, I think it is an okay game for kids way below that age. I just don't understand; Why not under 15 C.S.? Why? I just can't see it.
