Responding to Commissioner Frattini’s concerns over "violent video games" the video game industry has defended the EU's voluntary and independent certification system.

Suggested policy responses range from an outright ban to stricter self-regulatory measures and labelling than those already in place.

The issue was brought into sharp focus on 20 November 2006 when a German teenager, Sebastian Bosse, 18, stormed his former school, Geschwister Scholl in Emsdetten near the Dutch border, and wounded around 32 people with a firearm before committing suicide by shooting himself.

study, conducted in 2000 by Craig A. Anderson from the University of Missouri in Columbia and Karen E. Dill of Lenoir-Rhyne College, suggested that "exposure to violent video games will increase aggresive behaviour...in both the long and short term".

However, the 2005 findings of researchers Dmitri Williams, a professor of speech communication at the University of Illinois at Urbana-Champaign, and Marko Skoric, a lecturer at the School of Communication and Information at Nanyang Technological University in Singapore, appear to contradict the commissioner's position and "did not support the assertion that a violent game will cause substantial increases in real-world aggression".
