If you buy Diablo 3, you are just buying Diablo 3, you can play wherever you want. So you guys get to choose. Now what we will do is we will lock you down to a specific auction house, so for example if you are a European national you would have access to the European auction house. You will still be able to play in North America. You can participate in the gold auction house if you want, but you can only participate in the real money auction house of your native country [editor note: region]. [Another example] North American citizen, play anywhere, participate in the gold auction house anywhere, but the RMAH only in North America.
egarding different region clients: The download of the actual client will have no basis on where you can connect, all it's gonna dictate is what your language pack is... ... You wanna download the german client and play in Europe? you do that. You wanna download the german client and play in North America? you can do that too.
Q: So the functionality is closer to what Diablo 2 had where you could just choose server rather than Starcraft 2. Ye
D3没有像SC2的region lock,只是限制只能在1个real money auction house做交易而已,不过用in game gold买卖的auction house没有限制
