If you are even thinking of forming a company in the computer gaming industry, or if you're an outside developer presenting a game to a company, here is a wealth of information. Of course, as one of the contributor says, 'if you have $10 million already and you are starting a game company, then you can afford to hire a lawyer to do all this work for you.' But just to double check the work he is doing you still should read this book.
This book really has two sections. First is about starting a company. This is on all the general business parts like creating a legal business entity, renting an office, hiring staff, product and market analysis, raising capital, etc.
But then comes the second part that is specific to the gaming industry, especially the intellectual property that you are creating as you define characters, the art aspects of how the game looks, and the contracts you will need to have in place with your developers or with a game distribution company if you use them.
There's another aspect that could fit under either of these two as they are not standard for most businesses but not restricted to games either, this includes selling internationally, paying international taxes and so on.
Basically, as the title of this book says, it's a 'Primer,' that is, a general introduction that will enable you to know what you're talking about but not enough to consider yourself an attorney.
