People think they understand violence in the human animal. People are ignorant. Violence doesn't work the way most people think. Read this book to learn some truth and get some reality on board. I disagree with the very last part of the book. This book was written at a time when all experts agreed that the coming inevitable youth violence epidemic was going to be unprecedented, and these authors believed it too. Then... well, it just didn't happen. Despite hyperbole and professional handwringing, random street violence is at a half-century low. So, yeah, one failed prediction at the end of the book because the authors just don't really understand video games. Whatver. The rest of the book was masterful and fantastic.
This is, essentially the exact same review I have to give for "On Killing," and for the same reasons.
