The Market is a building in Age of Empires that features the ability to pay tributes to other players, and provides the ability to develop many useful upgrades that benefit the economy of a civilization. Most of these technologies found in this building increase the rate of resource collecting as well as ones that improve the food quantities of Farms. The Wheel is considered by some as the most useful upgrade since it makes villagers move and collect resource faster as well as enabling the development of chariot units.
