Since Monopoly was first invented, hundreds of different themes have been adapted to the concept of the game. This has certainly made the game more accessible to people who may not necessarily be interested in the straightforward concept of buying and selling in the game. By allowing - for example - a fan of the Beatles to buy 'Abbey Road Studio' as opposed to 'Mayfair', the concept of the game becomes far more appealing to a wider audience, and at the same time, the theme that is working in conjunction with the game is promoted and made more accessible to the general public in an amusing, informal way.
This is why I am applying the theme of 'Philosophy' to Monopoly.
Here are some weird and wonderful varieties of Monopoly that have hit the shelves in the past:
American Chopper Monopoly
Disney Pixar Monopoly
Be seeing you!
