The Mother of all maze games!
So yeah, Pac-Man was originally called Puck-Man in Japan. Either Midway or Namco wisely predicted that Americans would vandalize the word "Puck". So "Pac" became the norm. The name comes from a Japanese phrase "Paku Paku", which roughly means "open and close one's mouth, as if chomping down on something". I'm completely serious.

Pac-Man appeared at a time when the arcade scene was flooded with imitations of Pong and Space Invaders. The people wanted something new, and Toru Iwatani gave it to them: A maze game. But not just any maze game, THE Maze Game. The game that went on to inspire games like Wizard of Wor, Venture and Gauntlet. But mazes were hardly a new idea. What made Pac-Man stand out? I'll tell you...
Enemy AI. Iwatani intentionally gave each of the "Ghosts" (as they became known in the US) distinctive "personalities" that governed their movement. Despite their seemingly random movements, the Ghosts actions are in fact entirely deterministic. The Red Ghost is the "Chaser". He will run you down mercilessly. The Pink and Blue Ghosts are "Ambusher" and "Fickle". They will try to get ahead of you to cut you off. And the Orange Ghost is "Feigning Ignorance". The game's code suggests that his intention is to corral the player into a corner. However, all of this is contingent on a Ghost actually seeing you. The Ghosts can't see through walls, and they will follow a predetermined "patrol" pattern until their line of sight happens to intersect Pac-Man's position. Knowing this, it is entirely possible to avoid the Ghosts until absolutely necessary.
Fan facts:
There was a Pac-Man board game, produced by Parker Brothers, which I own. Each player's Pac-Man literally gobbles up marbles.
The highest possible score is 3,333,360. This takes into account every scoring opportunity, including the "kill screen", which occurs when the level counter overflows at 256. This renders the right half of the screen unplayable, but you can still play the left half.

Contrary to popular belief, the game Pac-Land is NOT based on the US cartoon series. However, when porting the game to the US, the similarity to the cartoon was so unmistakable that Midway altered the game's graphics to more closely match the designs used in the cartoon. This included adding in Sour Puss and Chomp Chomp, Pac-Man's cat and dog
Pac-Man is the most profitable arcade game ever, taking in an estimated $2.5 Billion in quarters.
The following exists, apparently. I'm as surprised as anyone.
