The plot is loosely based on Jules Verne's novel Around the World in Eighty Days. The year is 1872 and Monsieur Phileas Fogg has placed a wager at the Reform Club that he can circumnavigate the world in eighty days or less. The game follows the course of this adventure, as narrated by Phileas Fogg's manservant Passepartout, whose actions and decisions are controlled by the player. After leaving London on an underwater train to Paris, the player can choose their own route around the world, travelling from city to city. Each city and journey contains unique narrative content. The developers estimate that on one complete circumnavigation of the globe players will see approximately 3% of the game's 500,000 words of textual content. In their role as valet, players must manage finances, their master's health, and time as well as buying and selling items in different markets around the globe. The choices made by the player in story sections can also have a large impact on how the journey proceeds. The game has several secrets, Easter Eggs and hidden endings, with the rarest having been seen by as few as 3 players.
