The Werewolves of Miller's Hollow is a game I (Rachel) used to play a lot, 13 - 14 years ago. I'd take it anywhere with me and played it with family and all different kinds of friends. A game could be over in fifteen minutes or it could last for hours - political debates included. Time's have changed and there are so many other games in the genre to pick from, but Werewolves certainly is a classic for me! :)
