I have to agree, this game is very well done. I'm a huge Diablo fan as well, in fact I built the current computer to be able to deal with the 3rd installment of Diablo. If I can suggest, one game that I did really enjoy playing---Back in the early days of graphical RPG's one can't get away from the Bard's Tale without giving it a worthy mention.
The remake put out a few years ago in my humble opinion is worth a look. They had a lot of fun when they designed it, and some of the dialog options still make me laugh.
I'll be able to recommend this one, even though it has a few minor issues to work out? The game play and graphics/soundtrack is extremely well done.
