We all know running a horror game is hard but Dread is one of them rpg's that knew that and incorporated it into its mechanics. Nothing is more terrifying than pulling a block from a jenga tower when you know the killer is right behind you.
Now, for free, you can get a hold of a Stranger Things supplement to play a game in that setting.
I think this means you can play an rpg, of a TV series, where the characters play D&D...
“Stranger Dread doesn’t directly mimic the show (that would be boring for anyone who’s already seen it), but it does try to follow Stranger Things‘ lead in several respects, from the archetypal 80s-movie roles available for players, to the overall setup, where a child is snatched away to a strange mirror-world and his friends need to rescue him,” Frazier explained. “We’ve had a lot of fun with it thus far — I hope you do too!”
