E.T. the Extra-Terrestrial
After crashing down to Earth, E.T. must search around for the pieces of his "phone home" phone. If he finds them all, the mother ship will come get him and the game ends. But beware of the FBI agent who steals the phone pieces and the scientist who tries to capture E.T. When E.T. begins to lose his energy, find some Reeses Pieces to eat before he dies.
The success of the Spielberg movie launched this adventure game, and in turn the game was so bad it may have been responsible for crashing the entire video game market. Much hyped, rumor has it Atari ended up burying millions of copies of this in a landfill.
