The High Crusade is a 1983 board wargame published by TSR in Ares magazine #16.
The High Crusade is a game based on the novel The High Crusade by Poul Anderson, and simulates the rebel Crusaders attempting to overthrow the invading Wersgorix empire.
Rick Swan reviewed The High Crusade in Space Gamer No. 71. Swan commented that "With the demise of Ares, it'd be a shame if a great game like The High Crusade got lost in the shuffle. There are apparently no plans to reissue Ares games in boxed versions, so you'll have to round up a copy of issue 16 to get the game. It's worth the effort. The High Crusade is an absolute treat."
