One of the best resources for the indie game developer looking to create a commercially produced product. It's not a guidebook nor a hard and fast ruleset, but rather a list of lessons learned the hard way. Those kinds of lessons are difficult to come by without scrapes and bruises, so it is very much appreciated that he is willing to part with them for this price.
It's formatted very conversationally, but this helps to convey complex and frankly frightening concepts in a very approachable manner. Before reading this, I'd been stymied in how to continue to get my ideas into print. Now I feel like I can do it- it's still going to be hard work, and I'm sure I will make mistakes. But this makes the process not as opaque as it was before I read the book.
Worth it at 10x the price - experience can't easily be measured in monetary terms, but it's definitely worth $4.95 and more!
