Think of this as more of a research paper in book format, it hits all the major points and throws in some interesting examples. It's not terribly in depth, which is to be expect as it is listed as 'brief. I found it interesting but I don't think it would go on my 'recommend' list, unless someone asked me specifically for a super brief history. It would be good for those who know little about the gaming industry and want to brush up on it without being bogged down by a ton of excess information.
