3. Monopoly
Work your way round the board buying the iconic streets of London (in the original version), before building as many houses and hotels in order to bankrupt your opponents: you either love Monopoly or hate it, and believe it or not, this game was actually declined by Parker Brothers back in 1934, when they deemed it too complex and too long. They quickly changed their minds, though, once they saw how quickly it was selling from local stores, and it’s a good job they did – during its first year, Monopoly was selling 20,000 copies a week. Today, there are multiple versions you can play – including a junior version where you receive an allowance instead of a salary. The capitalist’s dream game is now estimated to have sold well over 250 million copies worldwide.
