I'm going to be playing in a game of Dread next week. What if anything do I need to have prepared? What do I need to bring (pencils, paper, dice, etc)?
You might fill about a character questionnaire at the start of the game, but that's about all the writing you're likely to do, unless you like to take notes. There is no need for dice or books of any kind. Dread is about as light as games get. There's pretty much nothing you can do to prepare for it, except practice at home with your Jenga set.
Pencil and paper might be helpful, but you shouldn't need dice. Dread uses a tower of balanced wooden blocks as its resolution mechanic; to succeed, you'll need to pull a block from the tower without it collapsing.
