The only thing I wish is that the game was about 3 hours longer.
I would say this about most of the one-shots that are showcased. There's only so many hours in the week and there's so many games to play, so it's not reasonable for RPPR to give full treatment to the games they play. I like to think that they're demoing the product and trying to get you, the window-shopping customer, to buy it and try it yourself.
I also think that something like Slender Man is only scary in still form with people making stories about him. Half the shit you saw in "Scary Stories to Tell in the Dark" wouldn't be remotely scary if played as an RP scenario. It's been mentioned before that something like Slender Man works best when you see him very little and know nothing about him or his motives.
But as Ross mentioned, cinematic monsters don't work that way.
Also... I keep imagining Slender Man without a face, so I have problems imagining him approaching a camera with frustration. He has no features!
EDIT: Also-also, I just noticed the post about the Little Fears: Night of the Squashed Cat game, which in the synopsis says that it's based on several of the "Scary Stories" stories. I gotta hear this now.
