I have used Marc as a headhunter before, I've found that like a typical sales guy, he really knows little or nothing about the game industry.He has no qualifications to write a book about the game industry. He can write a book about what skills would help HIM sell someone to a company in order to get them a job. Sadly, that's not the same as knowing what skills are required to KEEP the job.Basically, he wrote the wrong book.
