In a recent article on the progress of the Gun Task Force, it seems video games are still being blamed by the NRA for some of the violent acts performed in the US.  As a result of this, video game makers sent a letter to Biden requesting a recommendation that there should be additional studies made before any conclusion that video games are causing violent actions. 

One of the points IDGA (International Game Developers Association) makes in their letter to the vice president is this:

Game developers have been engaged in active and passionate discussions about our role in society and our responsibilities for decades, often facilitated by the IGDA. One way that game developers choose to recognize our responsibilities is by creating games with richer, deeper meanings in the lives of our audiences and by offering a wider range of experiences available than ever before.

For example, some violent games add non-violent options and solutions based on problem-solving and player creativity. Other games offer greater rewards for mercy and compassion. Many popular video games offer tough lessons in making better choices through interactive storylines that let players experience the consequences of their actions. And some game developers have responded to real world violence by creating games designed for conflict resolution, anti-bullying and aggression reduction. The government can help this process by supporting this unique, cutting edge research into harnessing the power of video games to help solve our nation’s problem with violence.

I believe making a recommendation against these games could have an adverse affect to our economy.  It seems there is a big market in the video game industry which include violent video games, so I'm sure the US will see a negative effect if such games are discontinued.

"The U.S. government did irreparable damage to the  comic book industry in the 1950s by using faulty research to falsely  blame juvenile delinquency and illiteracy on comic books," he wrote. "Censoring violent comic  books did not reduce juvenile delinquency or increase literacy, it  decimated the production of one of the few kinds of literature that  at-risk youths read for pleasure. Censoring video games could have  similar unintended consequences that we cannot currently foresee."

The other thing is this.  When purchasing a video game, there are all kinds of markings and symbols signifying a game contains violence, blood, sex, age recommendations, etc. and if these games are purchased by a parent when children are young, then they knowingly present these violent scenerios to their children via that media and a young child may or may not be able to learn the lessons presented in the games. 

"Unlike some industry groups, the IGDA  does not seek to impede more scientific study about our members’  products. We welcome more evidence-based research into the effects of  our work," he wrote, but added: "We  ask that any new government research look at the totality of imaginary  violence. Instead of simply trying to find negative effects, we ask that  any new research explore the benefits of violent video games, too."

IMO, the video game developers are right.  There needs to be more study on the cause and effect of playing violent video games.
