I can't really think of a better way to phrase it. Like having the "commentary track" on while reading through the book, it's very cool to see what Marc was thinking, references he felt were important to note, or how he tied in bits of his personal life into his writing.
In as much as our enjoyment of Traveller is about the setting and characters as much as it is about learning what Marc was thinking, I unreservedly recommend the audiobook package.
