For those going to NAVC, or wherever y'all were talking about having a get-together:
From the overview:
"After being attacked by an angry kraken, the One Winged Osprey is lost at sea. Food is running low for you and your fellow pirates, and there won't be a rescue any time soon. To make matters worse, there seems to be a group of cannibals on board, making their way through the crew at night, one by one...
Osprey Adrift is a social deduction game for 4 to 12 players and takes approximately 10 minutes per player to play. The core gameplay was inspired by the popular party game, Mafia (Werewolf), but offers a bit more strategy and a strong element of hand management."
ETA: Oops. Due date is Jan 2018 on it. So, maybe not good for NAVC if the due date slips a little. But still, appropriate for this crowd.
