As economy games go, Mombasa is well worth your money. Each player begins with an investment in a certain company, but over the game through careful drafting can invest in any of the other three companies on the board. You need to pay attention to the stocks other people buy as over time people have vested interest in every company. The theme is a decidedly awkward because of the colonial mandate in Africa for almost 400 years, but the designer casts off with a foreword that this is an economy game, not a simulation. The fudging the books option is just plain irony.
