I'm not sure if Cthulhu studies was an option when I was in school but it was most of what I did the last few years I was there.
Still a massive influence on my tastes in Gaming and literature now.. if there's tentacles and a thing that you probably shouldn't talk about and or never see, I'ts got my attention.
It was kind of a shame that at the Mountains of Madness didn't get picked up in the end. While I have a fear any kind of Hollywood take on the "Mythos" if anyone could of done it Del Torro would be been the man.
