"Monopoly" likely based on a game patented 30 years earlier

According to Hasbro, a salesman named Charles Darrow invented Monopoly on his own during the Great Depression.  However, some believe the world's most popular display of capitalism was actually an anti-capitalist game invented in 1903 by Lizzie Magie. Called "The Landlord's Game," the purpose of the game was to "demonstrate the evils of private land ownership." Some believe that Darrow likely played a version of the game in Atlantic City before pitching "Monopoly" to Parker Brothers as his own idea.
