Furnace is an engine-building Eurogame in which players take on the roles of 19th-century capitalists building their industrial corporations and aspiring to make as much money as they can by purchasing companies, extracting resources, and processing them in the best combinations possible. Furnace also includes capitalist cards that contain unique effects, and if you want, you can choose to deal one out to each player at the start of the game. For an additional challenge, you can require players to create a 'production chain', with each newly acquired company card being placed somewhere in that chain and locked in position for the remainder of the game.
