Political Game Theory

The following games are interesting because they abstract the essence of various forms of political interaction. They are even more interesting when you attempt to formulate (good) computer algorithms to play them.
Primitive Politics
a nasty game where only the "bank" is the winner.
Coalitions
an ugly exposé of internal party politics.
Log Rolling
a game which examines bargaining over multiple issues, also quite a fun card game.
$100 Dollar Game
a very simple game to examine cooperation among large groups.
