I am of course talking about Speakeasy, and you can read about it from the creator by clicking anywhere on this line/paragraph.
For those who finished reading the post before clicking the link - thank you, by the way - Speakeasy is a game like the party cardgame Werewolf. Players are assigned a role and must make moves to help their team win/succeed while accumulating personal points. The game has a moderator to keep things running, enforce rules, and help make special powers work. Unlike Werewolf, Speakeasy seems to rely on people being free to move about, talk, and interact with each other rather than the more structured around the table methodology of Werewolf. This is also where the more Role Play aspect comes in.
So, Like a LARP Then?
If I am reading things right, yes. Speakeasy works like a LARP. You have a game area, moderator, and players. The players interact freely and go to the moderator when they want to use an ability, make a ruling, or otherwise take care of things. Beyond that they go around, play their roles, and try to learn as much about the other team as they can mostly through things like learning passwords.
More than this and I'm going to be butchering the game as I'm not the creator. So head on over to the kickstarter page, take a look, and if you think its worth it put down some cash to help make this game designer's dream a reality.
