Great insight into an otherwise obscure world
Format: Hardcover
As someone who grew up playing blizzard's games for an unfathomable amount of hours I've always been interested into their inner workings, especially considering their downfall in recent years. This book holds a ton of information and knowledge, is well sourced, and is the work of someone with obvious deep familiarity with the industry and its particularities.
Besides the information itself, the book it written in fun and interesting prose, and it keeps the rhythm fast and entertaining, so it reads more like a novel than a journalistic article.
Overall, an entertaining piece of insight into a world that is normally quite unknown, even to long time gamers like myself.

Great insight on what happened at Blizzard but...
Format: Kindle
My main issue with the book is the lack of non-american stories that explained the bigger picture. As a former Blizzard dev, there's much more than what happened in Irvine and Korea, with Europe's office mentioned almost as a footnote, and nothing else from the other regional stories. Shame but I guess the book would've been double the size.

Insightful inside scoop of Blizzard
Format: Audiobook
An intriguing, well-written exploration of Blizzard’s history and its staff, from inception to modern day, and their design decisions, successes and failures along the way. I loved the many quoted insights, and learning more than just the surface level story that might be found on typical gaming news outlets.
