I've always loved to play monopoly. This is a very exciting and at the same time useful for the overall development of the game. It develops through oral, logical thinking, learn to develop a strategy to think about further actions a few steps forward. It also allows you to have fun with friends or family.
The monopoly is necessary to buy the street, and some "special editions" of the city, or the fabulous country. The larger cities of the player, the greater its chances of getting a profit. Sometimes it is not easy to choose and decide whether to buy or not to buy the city, preserve your capital or not. But when you take the right decision, you then feel like a real capitalist!
