The Campaign for North Africa (CNA), subtitled The Desert War, 1940–43, is a strategic board wargame published by Simulations Publications, Inc. (SPI) in 1978 that simulates the entire North African campaign of World War II. It is considered one of the most complex wargames ever published, with ten recommended players and an estimated total playtime of 1,500 hours. The game could not be fully playtested before release and it is unknown if a game has ever been completed.

yeah this seems like a 70s ill-convieved joke-performance-art-passion-project more than a real "game".
