I played an Outlander character some last night. Fun game so far, though I am still in act 1. Lots of the people who made Diablo 2 worked on the game including the composer, so the music is almost identical to D2, and the skill trees and leveling of stats are very similar. Haven't tried multiplayer yet. All the reviews I have seen have been very positive.
I'm going to be splitting my gaming time between this and Borderlands (although I suspect I will favor Borderlands). In any case, I downloaded it last night but haven't played it yet. Gonna play a bit today with an Embermage.
