I recently picked up this book at a thrift store just because I was surprised that such a subject got a book and since my fiance and his buddies are all in the video game arrangement and chiptune scenes, but much to my surprise, every place online that I see it for sale has it priced at 90-200 bucks. Unfortunately, though, I can't find any record in which it actually sold, so does anyone know anything about this book and how much it's realistically worth?
