Gamers can play in different countries but only pay at home
Blizzard has announced plans to divide the auction houses in Diablo III into country-based regions.
Players will be assigned to one of three auction houses based on the country of residence listed on their Battle.net account. The regions with an auction house available at launch include The Americas, Europe, and Asia; though the auction house for Asia will not use real currency for in-game transactions.
Blizzard’s Auction House for Diablo III will allow players to buy and sell game items for either in-game gold or real-life cash money (well, PayPal credit anyways).
Players have the option to switch their assigned region at any point in time, but real-world currency can only be used from a player’s home region. If a player decides to switch their region of choice, they will not be able to transfer any characters or items to their new region; each game region has its own independent hero and items list.
The official Diablo III FAQ page reads,“While you can access the gold-based auction house in any region in which you’re currently playing, the real-money auction house is only available in your ‘home’ game region.”
