I'm all about "The Thing" version of Werewolf, which I was introduced to while in France, by a Bulgarian.
It needs a moderator, so that's a slight downside, but the moderator gets to have a bit of fun. The premise is exactly the same as the movie The Thing. You all sit in a circle and are handed cards. A single one of the cards is marked, indicating if you get it you are the one containing the symbiote. The goal is simple, the humans win by killing the infected, the aliens win by having a greater number turned than the humans left. Each round operates as follows. Players go to sleep. The moderator walks around the outside of the circle and talks during this time. He indicates that the alien should wake up, signaling the player playing as the alien to look up. That player then selects a victim and indicates it to the moderator thru glancing. The moderator taps that person on the shoulder (a good moderator will continue to say that he is waiting for the victim to be chosen even after they have been). Note, that person does not wake up when tapped, so for the next part, they are unsure who infected them. So after an infected has been chosen, everyone wakes up. The humans get two "tests" to try to kill the aliens. So that is where the bluffing and deflection comes in. They majority vote on who to test, if they choose an alien, that player is eliminated. If the second test is unsuccessful, the sleep phase starts. From there on out, all aliens wake up and together chose a victim.
It's super ruthless. I'd throw players I'd just infected under the bus to save my own ass, since they had no idea I was the one that infected them. I'm proud to say I never lost as either alien or human (and I even started as the alien too) but it also means I'm apparently a damn convincing liar.
But yeah, we had werewolf in the mansion (was for this thing put on by Ubisoft, long story) but just ended up playing this almost every night for two weeks.
