One board game that starts with "m' is Monopoly.
On the Monopoly board, the property name "Marvin Gardens" is often cited as being spelled incorrectly. It should actually be "Marven Gardens," referring to a real place in Atlantic City, but the game uses the incorrect spelling. This has been a point of interest and discussion among Monopoly fans for many years.
My Guess would be Monopoly, the real-estate business game.

In Monopoly, the property that follows Mayfair in terms of value is Park Lane. Park Lane is the most expensive property on the board, and it is situated adjacent to Mayfair. Together, they form the most lucrative color set, the dark blue properties, which yield high rents when developed with houses or hotels.
Mayfair
£400
if you meant the most valuable property it is Mayfair the value goes up in order of position on board e.g. Old Kent road is the least valuable and is at the beginning and Mayfair is most valuable and at the end.
Mayfair is the most expensive property in British Monopoly.
Mayfair (not Mayfair Street) then Regent Street & finally Trafalgar Square.
Very much outdated but £400.
