I am not sure why this game was labelled a secret. I remember it coming out! I also remember it being praised for the AI but don't recall any of the reviews saying why it was so good.

I suspect we'll soon have an article about the secret Lucasarts game called Grim Fandango....

Douglas Adams wrote some interesting books (I fondly remember the 5 book series of Hitchhiker's Guide and listened to the radio show from my dad's cassettes) and thought Dirk Gently's first book was funny but lost interest in the second. I was surprised that this game was labelled as Douglas Adam's creation though - did he write any code? :-)
