It's not that the things in this book are wrong, it's that they are merely common sense, and there is a -lot- of repetition. Hey, if you're hiring people, you might want a contract. If you're starting a business, you might want an accounant. If you're making a game, you need a plan first. The polls have about sixty respondents each, and only two or three projects are examined 'in-depth'.
On the plus side, it is helpful to see some industry jargon in context, and to know what some publishers will expect to hear within 90 seconds if they're going to take interest in a product.
Bottom line, this book should not be 400 pages long and cost $40. You can find a lot of this stuff on message boards, or by just asking a programmer how his day was.
