I would describe the game, but that would be redundant for anyone that actually goes to the link.
We always play with a couple variant Villagers.
1. 1 Villager is a Hunter Villager. When he/she dies, the player may pick one person to kill. The picked person is out of the game.
2. 1 Villager is a Little Girl Villager. That player may peek during the Werewolf phase of night, but if the Werewolfs see her, she will almost certainly be their next victim. This has never happened in-game, but speculation has risen as to what would happen if the Little Girl didn't try to be secretive, and opened her eyes with the werewolfs, who would then have to quietly figure out who was pretending to be the werewolf.
I enjoy the deception in the game, but I'm usually the Moderator, as I'm the main advocate for getting people to play it.
Hope you enjoy it! (Assuming you can ever get a group big enough to play)
