Here is an interesting interview with "the man". While most of it is not specificly Demigod focused, still a good read though, the last part mentions "Chris Taylor will be at the Leipzig GC Developers Conference this week.
Today, he will join a panel with David Perry and Michael Capps to
discuss Best Selling Games, and on Wednesday he will present a session
entitled The Struggle for Independence and the Making of Demigod." We need to get that posted here as I am sure many will be interested.
