If you're interested in Blizzard history, there's a 4-hour interview with Rob Pardo hosted by Civ 4 lead and Offworld Trading Company creator Soren Johnson. Pardo also recounts the beginnings of Diablo in part one around ~1:27:00, although he wasn't involved in the project at that time.

Starcraft, WoW, and Hearthstone are also discussed. Warning: audio quality is not great.
