Easily the greatest game I have ever played, however it has a few problems that really make it inappropriate for younger players. The biggest problem in the game isn't so much the violence itself as it is the themes in which some of the violence occurs. For example, there are missions that involve killing innocent people for no understandable purpose and other missions that involve graphic torture and even things like human sacrifice and cannibalism. These horror-themed missions are pretty commonplace and they are hard to avoid unless you know what to look for ahead of time. In addition there are some graphic scenes of violence, such as the occasional beheading that occurs, which are also unavoidable. However, overall the violence is pretty mild when compared to most other mature-rated games. There is really no overtly sexual content, profanity is rare and drug/alcohol-use is moderate. All-in-all, I think kids twelve and under can safely watch their parent play this game or even play it themselves with a parent watching. Most teenagers should be able to handle the content in this game without supervision.
