What a fascinating book. It's a terrific idea to examine the iconic Atari 2600 in this way, and the authors do a good job of exploring it at the lowest levels. They make a good case that the physical hardware design directly influenced the design of some of the device's most famous (and infamous) games, and that those early design tradeoffs themselves led to certain conventions still apparent in modern video game design. The book's organized around several key game cartridges, each of which is a case study to point out some aspect of the technical or cultural impact of the Atari; it's a really good way to organize the narrative.
If you've only ever worked with "modern" graphic computer technology (i.e. anything with pixels), you'll be really amazed at what the Atari programmers were able to do with the unbelievable constraints they had to work with. One of the most incredible things I learned was that the system had only 128 bytes of RAM, not even enough to store this sentence in memory. In contrast, the cheap laptop I'm writing this on has more than 9 million times as much RAM available. That is an almost unimaginable difference in scale.
Unfortunately, the book is really poorly written. The two authors obviously divided the subject into cultural and technical sections, each covering their own turf. The book tends to go back and forth between these topics, so there are weird changes in tone, references to ideas that haven't been introduced clearly, and an annoying use of jargon. Overall, the book suffers from the academic tendency to try to point out even the most mundane and obvious details ("the joysticks were connected to the unit by cables") as well as a total lack of understanding what the reader may know coming to the book. So we end up slogging through technical sections that haven't explained basic concepts, even when it would be simple to do so, and when an understanding of those concepts is absolutely key to the argument. It's very frustrating, because any editor should have been able to catch this kind of mistake. An editor would have also been able to salvage the terrible chapter on Yar's Revenge, which feels like a jumble of first-draft notes and facts.
That said, it's still a highly recommended book. I can't think of anything else like it. I really hope this series on "Platform Studies" improves with future books.
