Secret Hitler

A social deduction game where 5-10 players are secretly assigned as liberals or fascists, with one player as Secret Hitler. Liberals try to pass liberal policies; fascists try to pass fascist policies or elect Hitler as Chancellor. The game generates more shouting, table-slamming, and broken friendships than any other entry on this list. The Kickstarter raised $1.5 million and the game is available as a free print-and-play, which is either brave or insane. It's banned from some game cafes for noise complaints.
