Charles Darrow adapted a version of 'The Landlord's Game' that had been circulating within Quaker communities. This version, which emphasized aggressive competition and wealth accumulation, became the basis for the game that Parker Brothers would eventually market as 'Monopoly.'

Parker Brothers initially rejected 'Monopoly' but later acquired it after seeing its popularity. They also bought Magie's patent for 'The Landlord's Game' for a small sum, effectively burying the original game and its critique of land monopoly.

'Monopoly' became one of the best-selling board games of all time, generating immense profits for Parker Brothers and its successors. However, Lizzie Magie's role as the original inventor was largely forgotten or minimized.

Researchers and historians began to uncover the true history of 'Monopoly,' highlighting Lizzie Magie's role as the original inventor and the game's original purpose as a tool for social commentary. This led to a reassessment of her legacy and her place in board game history.

Lizzie Magie's contribution to 'Monopoly' has gained increasing recognition in recent years, with articles, documentaries, and books highlighting her story and her original vision for 'The Landlord's Game.' She is now celebrated as a pioneer in game design and a social activist.
