Some good picks here. Lovecraft is good to read tonight too. That dude was way scarier than King or Barker could hope to be.
I prefer vid games on Halloween myself. I am getting to be a home body now that I am older, so no parties. I am thinking a little Doom 3, since it has been since the Fall it came out since I played. So the zombie closets should be fun for a bit. Definitely some Prey, really under rated game imo. One of the first? was for me anyways, that did the Yo we heard you like video games thing, with video games inside the video game.
Some Red Dead nightmare, and finish it off with Arkham Knight, which I just picked up with DLC for $15 last night, and evidently takes place on Halloween. Last time it was x-mas.
