If you have older children, chances are they’ve already asked you to get them a copy of “Grand Theft Auto IV.” So what do you do? On the one hand, the title doesn’t sound very kid-friendly. On the other, it’s just a video game—how bad can it be?

Well, as the parent, that’s your call. But help is available. The Entertainment Software Rating Board exists to assist consumers who want to make informed decisions about what kinds of entertainment they bring into their homes. (Perhaps you’ve heard of these folks; they’re sometimes referred to as “responsible citizens.”)

Of course, the ESRB’s rating system is no less nebulous than what you get from its cinematic equivalent, the MPAA. (E10+ is the game world’s ridiculously finer-point version of PG-13—I mean, what part of “parental guidance” did we not understand?) And because each parent has their own individual standards of what is or isn’t appropriate, the ratings are ultimately open to your personal interpretation and final judgment.

In other words, they’re there to help you, not to make decisions for you. As we’ve said before, “parent” is a verb, too. So be an active participant in your kids’ gaming choices by looking for the following symbols, which can be found in the lower left corner of every game box. (Please also note that a more detailed content warning can be found on the back of the box.)
