Labour MP and prominent anti-video games campaigner Keith Vaz has tabled a motion in the House of Commons, condemning Modern Warfare 3 for its violent content and calling on the British Board of Film Classification to take "further precautions" over violent video games.

 "This House is deeply concerned about the recently released video game Call of Duty: Modern Warfare 3, in which players engage in gratuitous acts of violence against members of the public; notes in particular the harrowing scenes in which a London Underground train is bombed by terrorists, bearing a remarkable resemblance to the tragic events of 7 July 2005; further notes that there is increasing evidence of a link between perpetrators of violent crime and violent video games users; and calls on the British Board of Film Classification to take further precautions when allowing a game to be sold."

"The game you refer to is a certificate 18 game," he said. "It should not be sold to children and the government's job is to make sure that adults ... can get what adults should be able to and children are not in danger of being subjected to adult content."

"Keith, for many year, has been very critical of adult content in video games and he's homed in particularly on the Call Of Duty franchise,"

"He's tabled a motion, about a week ago, condemning the game. I just amended it to make the point that the game has an 18 classification and that the BBFC said in a statement that it bore no resemblance to the July 7 bombings in London – which is what he refers to in his motion.

"There may be disturbing or unsettling content in that game, but adults should have the choice as to whether they want to play those sorts of games or not."

Watson says that he hasn't played Call Of Duty: Modern Warfare 3 yet, but he has booked time to play it during the Christmas recess as he's a massive fan of the franchise. He's currently playing Portal 2.

Neither Vaz nor the game's UK distributor, Activision, were available for comment.

"In all of entertainment, only Call of Duty and Avatar have ever achieved the billion-dollar revenue milestone this quickly," Activision chief executive Bobby Kotick said.

"There has never been another entertainment franchise that has set opening-day records for two consecutive years and we are on track to outperform last year's five-day global sales record of $550m."

''On the one hand, it glorifies the illegal assassination attempts the United States government planned against the Cuban leader … and on the other, it stimulates sociopathic attitudes in North American children and adolescents."

 "It contains such scenes of brutality that even the manufacturers have put in warnings within the game telling people how they can skip particular scenes."
