Diablo III is going to remove the gold and real-money auction house system from the game.
Diablo and Blizzard Entertainment initially designed and implemented the auction house system, the driving goal was to provide a convenient and secure system for trades. But after much review and player feedback, it became increasingly clear that despite the benefits of the AH system and the fact that many players around the world use it, it ultimately undermines Diablo’s core game play: kill monsters to get cool loot.
Diablo and Blizzard Entertainment are working out the details of how the auction house system will be shut down, but wanted to share the news as soon as Diablo and Blizzard Entertainment made the decision in order to give everyone as much advance notice as possible. Please note that the final shutdown will occur on March 18, 2014. We will keep everyone informed as we work through this process, stay tuned to Diablo 3.com for further details.
