Mafia aka Werewolf aka Assassin falls in the category of Role Playing Games under Party Games and is a highly significant game as far as learning the psychological skills of warfare is concerned.

The game models a battle between an informed minority and an uninformed majority by assigning roles to the "mafia-members" secretly so that the "townspeople" don't know who they are among them though they might have been given the information regarding how many of them are there.
