Wasn't it supposed to be Starcraft II that taught him how to murder children with guns (https://www.youtube.com/watch?feature=player_embedded&v=MHzTlkAGNIE)? So, wouldn't that mean we should be abstaining from playing RTS's loosely (or directly, I guess) based on Warhammer 40k? Either way, I'll be playing whatever it is I'm playing. If my box-that-can-run-Natural-Selection-2 was working, I'd be playing Natural Selection 2 (which is pretty much first person Starcraft II anyway xD). But, since it isn't, it'll either be Minecraft or the MMO-of-the-month.
Really, though, this is kind of like: "Known TV watcher murders large number of children, country abstains from TV in memoriam" or "Known book reader kills many, no one reads for a day to remember the fallen." I mean, not that we shouldn't be taking a break from our favorite pastimes occasionally, but wouldn't it make more sense to maybe: "Cities across the country hold candle-lit vigils to mourn the fallen in recent school shooting"? This way we aren't blaming anything and are actually showing support for the families who lost their children. Maybe save the blaming for when we aren't super emotional and can actually think through things.
