Oh God. If you think thats bad, try watching german news. At least when there is a school massacre in America, everyone has their own delusions about the cause: Drugs, South Park, Godlessness, Marilyn Manson, Liberals...
But if we have one nutjob shooting his classmates, what is the cause? The EVIL, NASTY videogames of course! Seriously, they react as if videogames came from the devil and turn everyone into Johan Ribert from "Monster".
Yes, you can be addicted to videogames, but since it's not a physical addiction, it really is unimportant unless you start no neglect your life. And those are the most extreme cases (exept for this Korean guy who died, but it was Starcraft, so you can't really blame him [/tasteless joke]).
Personally, I don't play MMOs because I don't want to pay over and over again and I think they are boring. I'll stay a fan of singlepayer.
