Monopoly has become “the world’s best-selling proprietary board game,” but the original game allowed players to cooperate so that everyone could prosper:

“With us in Jarrell’s cottage was Mike Curtis, an Ardenite who twenty years earlier had played a round of Magie’s original 1906 Landlord’s Game (one of his opponents, as it happened, was Patrice McFarland). The Georgist rules by which Curtis had played were known as the Single Tax set, and they went beyond having players simply pay rent into Magie’s ‘Public Treasury.’ They also aimed to teach the shared ownership of public goods. Under Single Tax rules, when the amount in the treasury reached fifty dollars, the player who owned the lighting utility was forced to sell it, and thereafter the utility cost no money to land on, as it was now publicly owned. This process repeated itself with the Slambang Trolley, then with the railroads, then with the Go to Jail space, which became a public college that, instead of sending players to jail, provided extra wages at the end of the game. After that, each fifty-dollar deposit in the treasury raised players’ wages by ten dollars. A ‘win’ in Single Tax, which Magie later dubbed Prosperity Game, occurred when the player with the least amount of money had doubled his original capital. ‘The Landlord’s Game,’ said Magie, ‘shows why our national housekeeping has gone wrong and Prosperity Game shows how to start it right and keep it going right.’ Curtis admitted that he didn’t think much of the game, pronouncing it ‘kind of boring after a while.’”
