Those currently enjoying the PC version of the loot-driven dungeon crawler can expect the studio to shut down of both the regular Auction House and real money Auction House as March 18, 2014.
Regarding this announcement, Blizzard released this video explaining the decision in detail. Check it out below:
Thankfully, to accommodate this upcoming change, Diablo 3 fans will be receiving a drastic overhaul to the loot system with the upcoming Loot 2.0 update. Players will see loot drops of higher quality which will have a higher chance to be geared to your character, though the quantity of drops will be lowered overall, similar to what you’ll find on the home console version of Diablo 3.
Diablo 3 is now available for the PC, Mac, PlayStation 3 and Xbox 360 platforms.
