Removing it from Walmart is probably the worst decision. Walmart is the only store that ever carded me when buying an R rated movie or an M rated game. I was just above legal age to buy at the time, but I went into Target when I was 15 and bought Soldier of Fortune 2. Which, by the way is arguably the most violent game ever made thanks to it's GHOUL 2 system in which you can literally blow people's heads apart piece by piece. If parents decide to buy it for their children at Walmart, that's their decision, but Walmart seems to be the only company I've ever seen that actually enforces ID policy when selling games and movies to children. I was never asked for ID when buying violent games at Best Buy or Gamestop.
