Day 28 — Scariest Game You’ve Played
I can honestly say I’ve never truly been scared while playing an RPG. I’ve been made terrified that my characters were going to die horribly, but that’s not quite the same thing.
As far as creating a mood of dark unease, though, Tomb of Horrors did it for me back in the day. More recently, I could mention the “Skinsaw Murders” section of Pathfinder’s Rise of the Runelords adventure path, which I was a player in earlier this year. It’s extremely and consistently creepy, and that’s a good thing in my books.
