Over at Wired.com, Clive Thompson's recent 'Games Without Frontiers' column is named 'You Grew Up Playing Shoot'em-Up Games. Why Can't Your Kids?', and he has a bit of a dilemma.

Specifically: "Gamers like me have spent years railing against ill-informed parents and politicians who've blamed games for making kids violent, unimaginative, fat or worse. But now we're in a weird position: We're the first generation that is young enough to have grown up playing games, but old enough to have kids. So it turns out that, whoops, now we've got to make sober calls about what sort of entertainment is good or bad for our children. And what, precisely, are we deciding?"

There's one particularly interesting perspective in there: "Chris Anderson, my uber-boss -- the editor in chief of Wired magazine and lead editor on Geekdad -- suggested a even more intriguing strategy: the "Lego Rule." The Lego Company, it seems, has a policy of not producing toys that replicate 20th century weapons. "You can have swords, and you can have laser guns in space, but no actual 20th century guns," Anderson says. So his four children can play games like Halo, since it contains only futuristic, fantasy war, where you're killing only green- or blue-blooded aliens. The same goes for Roman swordplay titles. "But it clearly walls off Grand Theft Auto.""
