Well that would depend on exactly how much of a disadvantage to the
ghosts the player anticipating the ghosts is.  In the original Pac-Man
it was possible to predict the ghost movements accurately enough to
for books to be published with the exact path to follow through the maze 
to guarantee a victory.  Essentially this means the pridictableness
of the ghosts was terrible disadvantage for them.  Adding a just a bit
of randomness, enough to distrupt any preplaned path, but without
making the ghosts too "dumb" may not be a bad idea.
