"Not really what I was looking for"
This is a very, very thin introduction to the major ancient civilizations. It is like listening to a short podcast, complete with cheesy sound effects and a narrator who sounds less than professional. The narrator has a flat, slightly irate-sounding voice and sighs repeated times. (Maybe he was yawning? I certainly was.)
Imagine a tired, slightly angry man reading Wikipedia for 5 hours, and chapters broken down by a musical flourish from a 1980's synthesizer and a loud, jarring "beep." Every two minutes or so. That was a good thing. The beep stopped me from falling asleep at the wheel while driving.
The content is too thinly skimmed over to really hold the interest of the listener. Like I said, think of an entry in an encyclopedia. If that's what you want, and you don't mind a grumpy narrator, this may be for you.
