 The game was originally intended as a 2-player game, but rule variants have been contributed by fans to allow 1 or 2 further players, causing Reiner Knizia himself to later provide semi-official 4-player rules.

Junta is a board game designed by Vincent Tsao published, as of 1985, by West End Games.
 Players compete as the corrupt power elite families of a fictional parody of a stereotypical banana republic (specifically "Republica de los Bananas") trying to get as much money as possible into their Swiss bank accounts before the foreign aid money runs out.
 Fighting in the republic's capital during recurrent coup attempts encompasses most of the game's equipment, rules and playtime.
 This game-within-the-game is however actually tangential to the players' main goal.
