The tie between the shooter and WoW is slim. But a new study over there says that 50,000 to 60,000 minors could be classified as addicted to videogames. And the combination of the two events is causing Ross-Luttman to call for stronger ratings on "addictive" games like World of Warcraft. It's also interesting to note that in the US, the game is rated T by the ESRB, which actually calls for children 13 and up to play it, one year older than the German standard.
But of course there are two conclusions here. First, every parent needs to take responsibility for what their younger children do: if these kids are addicted, parents need to step in and make sure things get straightened out. As a former employee of a gaming retail store, I can tell you that ratings only go so far. The responsibility has to lie with the parents. And secondly, while Ross-Luttmann is apparently using the shooting to try and push this agenda against addiction, the young man involved in the shooting was experiencing deep depression, and had access to firearms that he probably shouldn't have had. Changing game ratings is fine, but it won't do anything to help when you've got much bigger problems to deal with first.
