I tried the beta of this one, and I have to say, for an ARPG, it far exceeded any expectations that I had. I wish that D3 has been as well made. I should note that I hated the VH movie (did not watch part 2) and have no experience with the comic.
Having said that, it's still an ARPG, so not sure how long it would keep my interest.
(also in the beta) and while I agree it is very high quality it is not epic length so I'm a bit mixed. Also I'm not sure how the game will play out after act 1 (I hope the quests are a bit denser and areas more interesting). Titan quest (with expansion) was epic in length... Oh one other minor thing I wish you could rotate the camera.
