If you have children, and are a gamer, you have probably run into some awkward situations. There are some games that are perfectly acceptable for adults, and yet wildly inappropriate for children. Some parents may disagree, and buy Grand Theft Auto for their first grader, but for most of us, there's a line between what's a "me" game, and what's a "kid" game. This line varies from gamer family to gamer family, of course, and by child, as well. For my youngest, who is eight, we have a higher tolerance of sci-fi violence (such as that in Halo's campaigns) than we do human on human violence (Call of Duty comes to mind). Excessive realistic gore is a no-no (Left 4 Dead), but heavily stylized cartoon blood (Castle Crashers) is acceptable. For our older son, fifteen, all the above games are probably OK, but I'd draw the line at games with strong sexual content or excessive language. The point is, there are going to be some games on the shelf that your kids are not allowed to play.
