If you ask a teen what the "M" rating on a game means, he'll tell you: Hide it from Mom and play it with the headphones on. That's the good stuff. If it's not "M" it's probably "Hello Kitty's Cupcake Bunny Picnic Parade 2: Sparkle Love Rainbow Day" or "The Sims: Accountancy Fever." Audit books in real time across a network! Yeah, right.
