Banish the Snakes
Legend has it that St. Patrick drove the snakes out of Ireland. True, there are no snakes anywhere on the island- but there have been none since before the last Ice Age! The legend is actually an allegory about his successes in converting Ireland to Christianity.
Banish the Snakes is a cooperative game that simulates Ireland in the 5th century, while the Roman Empire was collapsing in the west and Ireland was turning to the Christian religion. Players represent Saints- Patrick and others (up to six of you) who set out to convert the pagans on the island. You must work as a team to convert the people of Ireland before the barbarians completely overwhelm Britain- if you fail, the Irish will not be able to save Civilization in the following centuries!
