Good game...but parents may worry about some content.
The only real concern about this game is that the female characters can be in skimpy clothing. And fanboys may be tempted to remove all their equipment (including clothing) in the Character Creator. Thankfully, there's swimsuits which cannot be removed. However, if parents don't want their child exposed to girls in swimsuits (except if their child is a girl), don't buy this game and wait until you feel this game is appropriate. But by then, it won't be made anymore, so just buy it now, and play it with your child until he's mature enough to play alone. Violence is moderate, but no blood or gore. Language is mild, but because some online players may have a PSEye (the PS3 webcam), kids may hear some strong language. Overall, it's good for everyone, but play it with the really younger kids until they're mature.
