Just a warning: Pacman is a clone of Puckman. And also some two-player versions of 4-player games are clones (important if you don't always want to be the first player character).
Better solution would be to make a gamelist (or numerous gamelists), which Mala does quite easily. Do you really want to rifle through ten thousand games (exaggeration, but "a lot") that are unplayable or genres you're not interested in (e.g. Majong)? You can then hide "ALL GAMES" for guests.
