You will compete against Andrew the Automata in this solo-only version of the game, which does not offer an online mode. The game features the original graphics from the board game, with the objective of helping you learn the rules and enhance your skills. Carnegie was inspired by the life of Andrew Carnegie who was born in Scotland in 1835. Andrew Carnegie and his parents emigrated to the United States in 1848. Although he started his career as a telegraphist, his role as one of the major players in the rise of the United States’ steel industry made him one of the richest men in the world and an icon of the American dream. Andrew Carnegie was also a benefactor and philanthropist; upon his death in 1919, more than $350 million of his wealth was bequeathed to various foundations, with another $30 million going to various charities. His endowments created nearly 2,500 free public libraries that bear his name: the Carnegie Libraries. During the game you will recruit and manage employees, expand your business, invest in real estate, produce and sell goods, and create transport chains across the United States; you may even work with important personalities of the era. Perhaps you will even become an illustrious benefactor who contributes to the greatness of his country through deeds and generosity! The game takes place over 20 rounds; players will each have one turn per round. On each turn, the active player will choose one of four actions, which the other players may follow. The goal of the game is to build the most prestigious company, as symbolized by victory points.
