What if Call of Duty was actually real? What if millions of teenagers/lifeless adults were actually running around killing people in Iraq and Afghanistan from the comforts of their living room?
Perhaps Call of Duty is really a government program to replace real lives on the ground.
SPOILER ALERT! DO NOT READ ON IF YOU HAVE NOT READ ENDER'S GAME.
Ender's Game, by Orson Scott Card, is the story of a genius boy called into a government program to "practice" killing their nemesis. The twist? Turns out the "practice training games" were real life. Ender actually annihilated an entire planet without knowing he was doing so. I won't give away the last twist (and it's a doozy). Go see the movie, or better yet read the book (you have six months, what else are you doing with your life?).
