Magie created The Landlord’s Game, which she developed as an implicit critique of capitalism and hoped would “let the children once see clearly the gross injustice of our present land system.” She was awarded the patent in 1904 and published the game herself in 1906. In 1932, Charles Darrow came across the game at a gathering with friends. He tweaked a few things, pretended he created it, and sold it. Magie ended up getting a measly $500 while Darrow made off handsomely. Even worse, Magie lamented that her beloved game became a celebration of capitalism.
