PacPC

If you remember the '80s, chances are you remember playing a game called Pac-Man. PacPC is a free clone that brings the hungry yellow dot and even hungrier ghosts to your PC's desktop. Just as in the original game, the object is to speed around the onscreen maze, munching dots and the occasional bonus goody on the way. Avoid the ghosts at all costs, unless you munch out on one of those really big dots: only then are the tables turned on those meddlesome spooks.
