Robot Airplanes, Computer Games and Boy's Toys

This Wired article makes me remember the warnings my parents used to give me about playing violent computer games. It isn't real, I would always say, and I would never do this in real life. But now the army has a computer game interface on a real weapon... Have you ever seen how violent us kids get in a computer game? What if we don't know (or forget) it is actually real?
