Darkfall's getting a new market system in this week's patch, according to a developer blog recently posted on the game's official website. Markets will initially be available in the four NPC capital cities, but Aventurine plans to add more in the future.
Markets feature an order system, so players can place and fulfill both buy and sell orders, or even use the new system for player-created quests. "New players looking to earn gold can work to fulfill buy orders that are available," AV explains.
You can browse the market from anywhere in the game world simply by using the appropriate GUI button, but placing and fulfilling orders will require a trip to one of the capital market buildings.
