I picked this book up through a series of highly fortunate events, and have not regretted in the least the purchase. I agree in part with another reviewer who said that you have to read the book at least twice to understand it: That is not a down side to the book at all.Wark's understanding of what gaming can and should be is wonderfully expressed. The ideas are complex, accessible, and continuously thought-provoking. I shared excerpts and themes from it to my high school video game class, and though they didn't catch everything, they understood a lot. I wish there were more than just five stars I could give to this book.It should be noted, however, that there is definitely a lot of theory in this book (which makes sense, given the title). It requires thought to go along with it--just like any good game.
