82. Pac-Man (Arcade Version)

This is one of the games that made arcades legendary, and one of the main reasons anybody ever went to one to begin with.  Even when people were playing Street Fighter in the early 90's, this early 80's classic would still have people playing.  This game was found in laundromats, pizza shops, and arcades, and made countless businesses plenty of quarters.  I still have no idea if they had to share royalties or not.
