Tremendous; what a great, foundational work covering both hobby and professional gaming (and identifying some overlap between the two). Some of the references are a bit dated - this is a reprint of a 1990 book - and it would be enlightening to see some of the games of the past 30 years referenced in this context. There are also some weird formatting issues/choices in terms of changing fonts and font sizes and the footnote structure, but that's a minor concern.

In short, if you're at all interested in the value and utility of practicing and evaluating the decisions made by humans, and the interactions between them, this is a must-read. ( )
