This book was written for people who have heard about online "synthetic" (the author avoids using the over-hyped term "virtual") online worlds such as "World of Warcraft" or "Second Life", and are curious, but assume it's just some nerds in basements, not tens of millions of "ordinary" people engaged in near-billion dollar economies.

If you already have a rough idea of what's going on (you don't need to be an active "citizen" in any of these worlds for that), then the book doesn't have all that much to offer, though there is a great chapter on economics that discusses strategies for avoiding inflation ("MUDflation"), and the chapter on politics may stimulate some thoughts.

The book could have been more interesting if the author had been able to go into more detail and compare different online economies, and get an insider's perspective on why it is that things are the way the are (incl. failed experiments etc). I'd also have liked to see a less shallow discussion of the psychology behind all of this -- is the reason people kill each other online when they can just because that's the nature of humans, and is the reason South Koreans are way ahead online simply down to bandwidth rather than cultural differences?

The book is also (inevitably) a bit outdated. The author frequently mentions how virtual items are traded on Ebay; Ebay prohibited sales of items from World of Warcraft and EverQuest beginning of 2007. There is no mention of the "farming" phenomenon. And I was surprised that the book didn't mention Second Life (which I'd imagine should be more interesting than most fantasy worlds from an economist's point of view) much except in passing.

It is impossible to change the address when you first have placed the purchase. It makes it difficult when you the moment you buy the book discover that you made an error (wrong address), and then it is already to late to change the address. What can you do? Probably nothing, other than accept that you lost your money, and buy the book elsewhere.

Were this book explicitly a marketing tool for virtual worlds, I would say job well done. But as a work of scholarship, it is downright embarrassing. The only thing I have to say for it is that the economic analysis in part II does not seem patently ridiculous, but the same cannot be said about the political analysis, and both are predicated on the validity of part I's predictions of the growth and impact of virtual worlds. His logic explaining this predicted growth can only be referred to as spurious.

Published in 2006, this book is already dated, and in ways relevant to the author's predictions. His prediction that passive TV watching will decline in favor of virtual worlds is only half-true: instead, we have a flourishing YouTube where people interact with passive media by creating more passive media. The niche of on-line communication medium has been filled by social networking sites. The author predicts that people who grow up with technology will be drawn to virtual worlds, but this has not been the case. The adoption rate of virtual worlds among teenagers pales in comparison to the use of text messaging, social network sites, and other available technologies. This comes as a surprise given how inherently compelling he portrays these virtual worlds.

Castronova does not seem to take into consideration the reality of differing preferences. He claims the "natural" place for getting together is cyberspace, and there's no reason to type when you can talk. This kind of thinking permeates his discussion of the future growth of synthetic worlds. Because they can offer, for a certain value of "offer", interaction with a potentially more pleasant world, this does not mean that everyone down on their luck will flock to them-- regardless of how realistic the worlds may get. I think it would be difficult to argue that even enough of a critical mass for the phenomena he describes in part II has the right kind of inclinations to "live" completely in virtual worlds.

Castronova frequently employs the rhetorical device of referring to these worlds and everything about them as "real". Certainly, they are "real" in the sense that they are something that people occupy their actual time with, but this does not make them "real" in the sense of an equal alternative to actual life. Throughout the book he uses terminology to blur the line between the two meanings of "real", presumably with the goal of validating his claims about the importance of virtual worlds. He talks about it as a "way of life", about the players as "migrants", and that they have the "potential to become permanent homes for the conscious self" (p. 238). He claims game makers should allow avatars to have all the same human rights in-game as their players do in the real world. It's an argument that only makes sense if you accept that there's no fundamental difference between virtual worlds and the real worlds, and that's a claim that has a much higher burden of proof than his tricky rhetoric can meet.

Virtual worlds are a hot topic, and the buzz surrounding them has allowed a scholar to put out absolute crap, assured that the audience will call it "stimulating", "important" and "insightful". If you're going to read this book, cut through the hype and read with an eye towards the logic of his argument. But other than as a first-hand view of the type of faulty reasoning used to convince people that virtual worlds are the Next Big Thing, it's not worth the read.

To be honest I was expecting more on this book.It didnt tell all the info I wanted to know and the author focus too much on 2D games like Everquest and not so much in 3D games like Second Life.In most of the book the author is a little superficial in his analysis,he could go deeper.However the book is good for people who wanna have a general idea about on line games,specially Everquest,World of Warcraft and Star Wars.
