Paranoia is a
dystopian science-fiction tabletop
role-playing game originally designed and written by
Greg Costikyan,
Dan Gelber, and
Eric Goldberg, and first published in 1984 by
West End Games. Since 2004 the game has been published under licence by
Mongoose Publishing. The game won the
Origins Award for Best Roleplaying Rules of 1984 and was inducted into the Origins Awards Hall of Fame in 2007.
Paranoia is notable among tabletop games for being more competitive than co-operative, with players encouraged to betray one another for their own interests, as well as for keeping a lighthearted, tongue in cheek tone despite its dystopian setting.
