Two US politicians have introduced a bill that, if successful, would require most video games packaged in the United States to bear the label: ""WARNING: Exposure to violent video games has been linked to aggressive behavior."

As reported by The Hill, the Violence in Video Games Labelling Act H.R. 4204 is intended to draw attention to the claim that playing violent video games can have a lasting psychological effect on children.

"Just as we warn smokers of the health consequences of tobacco, we should warn parents – and children – about the growing scientific evidence demonstrating a relationship between violent video games and violent behaviour", stated Frank Wolf, U.S. Representative for Virginia.

"As a parent and grandparent, I think it is important people know everything they can about the extremely violent nature of some of these games."

Games industry trade body The Entertainment Software Association has responded by way of website Game Informer, calling the bill "unconstitutional".

No information pertaining to specific studies on either video game violence or the effectiveness of warning labels has been cited by supporters of the Violence in Video Games Labelling Act at this time.
