More Theory than Actionable Advice on Game Design
Format: Paperback
Not a bad book, but not what I expected going in. I read this for a bookclub like event on twitch. I thought there was going to be actionable advice. Like 'do X to make Y feel". The introduction points out that the book is not about the emotional feelings a player receives from games, and this is true. The book DOES provide a language for discussing game design at a more academic level. It is about the theory of how a game feels, and while I didn't agree with everything Steve wrote it was easy enough to follow the thoughts.

MUST HAVE for game devs
Format: Paperback
Fantastic book about the theories of what makes a game feel good and fun to play. I'd be doing the author a disservice if I attempted to explain it myself, just purchase the book and read it for yourself. Written very well and easy to understand even while going into very complex and intricate explanations. I'd say that this is a must have for any game developer. Hell, even for those who are just interested in learning more about games.

Great Reading, Mind Opening
Format: Kindle
This is a terrifically interesting and entertaining book, which presented me with at least two blockbuster ideas that changed the way I think about the past. I'll get to those in a minute, but first a few general points. Charles Mann is a science journalist:who seems to specialize in BIG topics. His 2005 book ("1491", which argues that the pre-Columbian population of the Americas was much larger and more sophisticated than generally assumed), was very well received. I enjoyed it so much, and thought it so valuable a book, that I was very anxious to read "1493". "1493" lived up to my (high) expectations. Mann is remarkable writer, with an extraordinary ability to present very complex facts and ideas in way that's not just accessible to the lay reader, it's fun for the lay reader. This isn't to say that the book isn't carefully researched -- the text is followed by almost 100 pages of footnotes, and throughout he cites and acknowledges the scientists and others from whom he has drawn information. It's just that Mann manages to combine a myriad of facts and hypotheses into a compelling narrative. And he often puts this in very concrete terms, focussing on individual people, commodities or events. It adds up to a fascinating read. It is also a very important one, with implications for the future as well as about the past. Mann's subject in this book is the Columbian Exchange, the sudden movement of plants, microbes, animals and people between the eastern and western hemispheres after Columbus' voyage to the Americas in 1492. A well known effect of this was the eastern hemisphere adoption of western hemisphere foods (tomatoes, potatoes, chocolate, coffee, and on and on). Another effect that's only been recently come to be widely understood is the devastating impact on the pre-Columbian population of the Americas; as many as 80% died in the epidemics that followed the introduction of diseases to which they had no immunity. But the population die-off and the exchange of plant species are not the only effects of the Columbian Exchange. Mann's book explores the myriad ways in which the Exchange -- globablization -- has shaped the world of today. Two things I learned from the book struck me particularly. First, like most Americans of my generation (older) I learned in school that the colonization of the Americas was carried out by white people, who moved into a largely uninhabited continent. "1491" took care of the uninhabited: "1493" takes care of the white. Mann says that from 1500 to 1840, about 3.4 million white Europeans emigrated to the Americas. Over the same period, about 11.7 million captive Africans were sent to the Americas. Except for New England, much of the United States and most of Latin American was far more black than white. (And probably in 1840 still more Indian/Native American than anything else). The racial balance changed as white immigration ramped up and as millions upon millions of blacks died too young, but the picture of early America looks very different to me now. Secondly, Mann discussed at length the 19th century ecological disaster that engulfed China. I had always assumed that the floods that killed so many millions in China had always happened, and were the result of geography. There have indeed always been floods, but their severity and human cost grew logarithmically in the 19th century. New crops led to more food and to rising population growth, and at the same time to more potential cash crops, increasing the pressure on existing land holdings, and leading to vast land clearances. That made the floods far worse when they came, undermining the political structure and compounding China's problems. This was interesting not just a light on the past, but as a warning signal for the future. The review is already too long, so, to sum it up: Great book!! Read it!! Give it to friends and family!!
