Sometimes funny and imaginative, this travel guide also becomes repetitive in time. And most of the humour to be found in the commentary, is on the same level as Barry Trotter and other teen-ish parodies. So while the worldbuilding itself is interesting, the commentary (except for the editor's footnotes) isn't. One should have used the editor as author. The short takes on misogyny, racism, 'history is created by the victorious party', human tendencies to devalue anything they don't understand,... are really something and should have been expanded. Though I guess, with the author (the one inside the book, not Mr. Crowley) being a fully grown jerk, and biased as hell, this book follows the tradition of most major works of SF/F (and might at the same time be a commentary on a number of fans). So while it was annoying to me, this might have been a well-considered way to make a point, too.
