I had this on audible, and listened to it a long while back but forgot most of it. I'm about half way through again already. It's no Console Wars for sure. I hear you on the metaphors and similes, there were some I couldn't even follow because I wasn't familiar with the person he was referencing.
The part where it talks about how Charles Martinet was hired to voice Mario on a machine called the MIRT (Mario In Real Time), I realized that I had encountered that before. It was sometime In the early 2000's at the GameStop managers conference. In Nintendo's vendor training room they had this screen with an animated Mario head (sometimes it swapped to Wario), Charles Martinet was on a mic somewhere behind the curtain and was voicing Mario joking around with everyone. It was very cool. Later on at the expo I got and autographed pic from him.
