For the curious, I did stay awake for the Diablo 3 unveiling ceremony. I miscalculated time zone differences, so the ceremony started at 2:45, which was more sensible-seeming than 3:45. It was a fun time, even if it's a bit silly sitting alone in my home and yet feeling like I'm part of something in France.
People can laugh, but I honestly feel that Diablo 3 is a pretty significant cultural event. As far as I'm concerned, Diablo 2 was one of the great masterpieces of art that has been created in my lifetime, so anything new with the Diablo name is noteworthy. Certainly more interesting than, say, an award-winning play.
