The latest EconTalk is Edward Castronova talking about his new book, Exodus to the Virtual World. He argues that people will increasingly spend time living in the virtual world, playing these large-scale multiplayer real-time games such as World of Warcraft and Second Life. Very interesting. He then explores the implications for the "real" economy. I was skeptic at first, but I think he is on to something that most of us who don’t play these games are missing.
The book is superb, full of interesting observations about this world and the virtual one.
