Is... this an article about copypasta? And a good one to boot? Oh Escapist Magazine you silly bugger, what'll you come up with next?
Pokémon Ghost Black is a cool story (bro) (it taks about goshts and doesn't afraid of anything) (OVER 9000 MEMES) but it is part of a much greater genre of creepypasta, which is always about taking these loved mementos of childhood and turning them into horrible harbringers of evil. But unlike the rumors that Mr. Rogers was a child molester, its intent is not to sully the memento itself, but its influence in our life. It asks, what if the thing that shaped your life, that you look back on so fondly, is actually evil?
It reminds me of Borges' Pierre Menard's Don Quijote. (Now that sentence is a handful.) Can the same element, introduced in a different context, be completely different? I always read that piece as mostly a biting critique of literary analysis, but like most of Borges' work there are layers and layers of analysis.
I think the prevalence of the creepypasta (yes I will continue to use that word as if it was a scientific term, DEAL W IT) is essentially a way to break from our protective shells. Every generation of children is more overprotected than the previous ones. Not content with breaking away from our parents, we must retroactively cause them to fail, by repurposing the mild things they did allow us to play with as dark and dire. The darkness was around all along, and we were lucky to not have slipped in.
The embrace of videogames as a media is secondary in this case, there are similar creepypastas relating to cartoon shows and things like that, although it's also worth of an analysis. I'm thinking of creating a work in this vein as soon as I get off my fat ass. Happy 2011.
