NEW YORK - Imagine this video game scenario: Assigned to rescue the embattled squad you've fought with for the past 10 hours, you fail miserably. You have nothing to show save for a torn piece of clothing, bloody at the edges. As the soundtrack reaches its crescendo and the words “Game Over” materialize over the mists of Planet X, it's not frustration you feel, but regret, sadness, even, for those brave soldiers you left behind.
