Who could ever forget the first time they played "Pac-Man?" That yellow sphere trapped in a blue and black maze eating yellow dots and running away from four brightly colored ghosts? That introductory music and the "wacka-wacka-wacka" noise when he ate the dots? Invented by Toru Iwatani (who was inspired by a pizza missing one slice), Pac-Man went on to become one of the first video games to feature an endearing central character. Another neat fact is that the original name of the character was "Puck-Man" but this was changed once the game hit the states to prevent vandals from scratching an inappropriate word from the title. Pac-Man has seen it's share of sequels, cartoons, and merchandising. Incidentally, good ol' Pac is celebrating his 25th anniversary.
