Gamasutra - How Blizzard Makes Games
Christian Nutt of Gamasutra has posted an article that takes a look at how Blizzard makes games like Diablo III. So if your curious about the process read the link.
How does Blizzard maintain its game quality? By refusing to compromise and by understanding that "core" and "casual" are not hard-and-fast distinctions, but two ends of a spectrum. That's according to Jonny Ebbert and Tiffany Wat, lead console designer and associate producer for Diablo III: Reaper of Souls - Ultimate Evil Edition. The game is soon to come out on PlayStation 4 and Xbox One, and has gone through a number of refinements (and a full expansion) since its original release on PC a couple of years ago.
