From the back cover:
This book not only allows players to make the most of Merchant character but also adds several new elements to the rest of the Traveller gaming system. Where some players may want to earn their living dodging bullets and spending as much as they make on armour repairs, some enjoy a more social or economic approach that can be just as exciting.
This sourcebook provides a host of new options, rules and plot potential. Traveller fans can find new boons within the game's economy based career paths, the companies they create and the market they live and die for.
Merchant Prince is a guide to making a fortune using the tenets of the merchant class.
