My favorite game, still to this day, is the original Pac Man.
Did you know that the original name for Pac Man was Puck Man? You'd think it was because he looks like a hockey puck but it actually comes from the Japanese phrase "paku-paku" which means to flap one's mouth open and closed. They changed it because they thought Puck Man would be too easy to vandalize - you know - like people could just scratch off the P and turn it into an F or whatever...
