The parties were beyond amazing. I met Wyatt Cheng (Diablo III - Senior Technical Game Designer) at the Steam party and he invited us to the Blizzard party the following evening. We were extremely impressed by the scale of the Blizzard party. The food and atmosphere were amazing, and there were so many awesome people to talk to. I spent three hours talking with Jay Wilson about game design. He was kind enough to take a photo with me, which I promised I'd post to our community. Jay and Wyatt are both really humble, nice guys. They explained in detail what lessons they learned from the development of D3 and gave up a lot of their free time doing so.
Speaking of Diablo developers, we also had dinner and drinks with Max and Erich Schaefer (of Blizzard North/Flagship/Runic Games). We took a photo with them too (from left: Rhys Abraham, Erich Schaefer, Chris Wilson, Jonathan Rogers, Max Schaefer). We've known Max for a few years now, so it was great to catch up with him and to meet Erich. It's hard not to act like a fanboy around the guys who created Diablo II.
