I actually shelled out for the invisible-ink "strategy guide" (i.e. cheating instructions) just to finish the damn thing. I suspect the guide was written by Adams as well, because it was almost as entertaining as game itself. Halfway through the section on how to get the Babel fish—the single toughest puzzle I’ve ever encountered in a game—it tells you that "it is at this point that grown men begin weeping uncontrollably."
