Les Bâtisseurs - Antiquité is a stand-alone card game based on The Builders: Middle Ages. In it, players score points (and gain money) by completing the construction of buildings, while placing a worker on a construction site costs money. Each building has four characteristics (carpentry, masonry, architecture, painting) rated between 0 and 5, and the workers have the same characteristics valued in the same range. To complete a construction, the player must add enough workers to cover the four characteristics of the building. Differences to The Builders: Middle Ages include: - The possibility to take credit - Slaves, these need not be paid to be put to work but they will cost negative points at the end if they are not freed - Tools, players can acquire tools that can then be given to workers to increase their characteristics - University, workers can learn at the university and increase their characteristics.
