The addition of auction houses made it quite convenient for players to exchange goods. They have evolved over time from static locations with interactive auctioneers to, in some games, the ability for the player to buy and sell goods anywhere in the world. While this feature is quite popular (especially for pack rats like me), it has come at the cost of decreasing socialization between players and possibly, an increased sense of disconnection with the game as a world, rather than the world as a game. Again, a great feature for some games but in CU, we will have no auction house (though a commodities market *may* be an option due to the difference between gathered resources and crafted goods). Instead, crafters will control shops that they can run themselves or they can barter their goods in parts of towns that we have customized and optimized for that specific purpose.
