Adaptation Overdosed: Not even taking the sheer number of Themed Stock Board Game versions or altered official versions into account, Monopoly has an utterly absurd amount of video game adaptations, nearly once a generation and sometimes more. It began with the Sega Master System version in 1988 and there have been new ones put out at a steady consistent flow since. One can possibly owe this to the fact that the game benefits tremendously from becoming electronic, as it cuts out having to handle all of the paper money that is constantly on the move during the game and greatly simplifies the auction process, and being the most recognizable board game in history doesn't hurt either.
Easy Money by Milton Bradley. Officially, both games are based on an older game called The Landlord's Game, but Easy Money was released as a direct response to Monopoly's success. Continues to be published, under license, by a third party company.
Saidina is a Malaysian Foreign Remake of Monopoly going by a different name, with the settings changed (e.g. London -> Kuala Lumpur). Gameplay-wise it's pretty much exactly the same (right up to using identical tokens!).

What Could Have Been: Marc Summers and Peter Tomarken are two well-respected emcees, and they were in 1990. The success of Double Dare meant that Marc was busy elsewhere, though, and Peter's clash with producers over Patty's role being treated as a thing rather than a person meant that he was gone as well.
