Watching the video my overwhelming thought was "What the FUCK are you THINKING Infinity Ward"
Don't get me wrong, I see the statement they're trying to make, and it's bold and admirable. "Modern war is ugly and savage, and not just entertaining shootouts." But...that can't really expect anyone in the mass media to understand what they're saying, can they? All that people are going to take away from this is that it's a terrorism sim where murdering innocents is a form of entertainment.
It wasn't the scene of storming an airport being programmed into the game that appalled me, it was the player voluntarily joining in and gunning down civilians as they were trying to crawl away. Because the game isn't MAKING kids into bad people...it's showing us that they already ARE. Maybe people will argue that it's just a game and not a reflection on the player to kill imaginary innocents for no other reason than wanting to shoot at something while moving through the level, but god...the game is designed for maximum immersion and realism. It's not the mindless, easy, stupid violence of GTA or Fallout; you're marching deliberately through an airport machinegunning people with all the indiscriminate prejudice of a highschool shooting. If that isn't some reflection on the player, what is?
