The game has upgrades to increase the rate of collecting these resources. Marvellous dad we love you three thousand shirt. Players can build markets to exchange resources. They can use wood, stone and food in exchange for gold and use gold to buy other resources at the market. Market prices fluctuate through each transaction. In addition, the harbor or market can also produce gold by using commercial ships or vehicles to deal with allies. When commercial vehicles return to their ports or markets, the player’s gold volume will increase. The amount of gold that ships or business vehicles earn from each trip is related to the distance to the allies’ base. The farther you go, the more gold you’ll earn. Players can also trade with enemy ports or markets. However, the commercial vehicle of the player may be attacked or destroyed by enemy units on the trading line. Commercial transactions are done automatically, meaning that whenever the player selects a port or market, the business units will conduct transactions at that location in subsequent times. There was an improvement over the previous version of Age of Empires, when the market did not play a commercial role, but merely a building with technology to upgrade. For maps without sea, when a resource is exhausted (usually gold) it is not possible to use other resources to exchange.
