Iopred: Yup. And hence why my description includes some randomness. IN the real pacman, only 1 ghost (the red one) is smart and seeks you out 99% of the time. He's also a slight bit faster than Pacman.

The rest will occasionally head toward you but occasionally head in other directions, thereby at least giving you a chance to escape. And one of them is kind of dumb and rarely heads in Pac's vicinity.
