I also remember that each of the four ghosts had his own personality.

"Pinky":  The Pink ghost was extremely fast.  Pinky wasn't very smart,
but if he saw PacMan, PacMan was dead.  However, if he wasn't too close,
he was pretty easy to shake.

"Blinky":  The Red ghost was slower, but extremely tenacious.  He would
not ever lose the trail of PacMan once he found it, but he hardly
ever found it.

"Inky":  The Blue-green ghost was the one Gordon describes.  He had
a blind spot, and could not tell he was being followed.  Almost as fast
as Pinky, but not quite.

"Clyde":  The Orange ghost was the smartest, but he was very slow.  
Clyde would try to lay traps for PacMan by working with the other ghosts.

These descriptions were from what I remember of a "How to beat" book
on PacMan.  However, it was no less than ten years ago when I read it.
