Major German department store Galeria Kaufhof, part of the Metro Group, has decided to stop selling mature-rated video games and films, following a high profile gun attack in the country. Starting in April, the store will no longer stock any video games or DVDs with an 18+ age rating. The move comes after a 17 year old former student killed 15 people at a high school in southern Germany, with media and politicians later emphasizing his interest in video games such as Valve’s Counter-Strike. Although Germany already has one of the strictest ratings systems in the world, with many mature-rated games being heavily censored or banned outright, the incident has seen renewed calls from within Germany to ban violent games altogether. "I think [Kaufhof's decision] is a complete overreaction ... it borders on impulsive hysteria," said Stephan Reichart, managing director at German video game developers association G.A.M.E. to Reuters. "It would be sufficient if retailers made sure their cashiers don't sell this material to young people," he added.
