If you were wondering how they came up with the idea to do the Lords of War series, Blizzard has a pretty awesome video for you to watch, up on IGN now. This behind the scenes look into the development process of the Lords of War series is interesting for what you find out you didn't get as much as for what you did. I also loved finding out that Maraad is voiced by Crispin Freeman, aka Red Arrow from Young Justice. It's very cool to get to see him explaining what he's up to in the story, and in general I liked getting to see what went into the making of this video series.
You should definitely check it out. It's up on IGN right now.
