So it's confirmed that the Diablo 3 will have Unique weapons. It's a tradition in older Diablo titles and the new one that they making to create weapons with their unique animations styles.
In diablo I and Diablo II every Unique weapon had their icon and of course. They were grand, powerful looking weapons far beyond all the others.
This weapons did not extend more than the normal inventory.
So now your unique weapons will no longer seem like the other-similar.
