E.T. is considered by many to be the worst game ever made in the history of video gaming.  The game was licensed in 1982 and released just before Christmas after almost no time for development of the game itself.  Atari thought that with the success of the movie, the game would be one of their biggest sellers, so they produced millions of copies and sent them out to the stores.  It flopped.  It bombed.  It sold poorly...but it did sell.  There are copies of this game everywhere.  It is usually valued at a higher price than Combat (which was issued with the system for many years), but it seems to me that there are almost as many copies of E.T. floating around out there as there are of Combat and Combat is (in my opinion) more fun to play.

The idea behind the game is you are E.T., the Extra-Terrestrial.  You are stranded on Earth and in order to get home, you need to find the pieces to your phone.  Once you have found them all, you call the mother ship which will come and pick you up.  Along the way, you must run from scientists and FBI agents, pick up Reese's Pieces and find your Earthling friend, Elliott.  You fall into pits which you can get out of by pressing the fire button which extends your neck and allows you to fly.  If you find a dead flower in one of the pits, you can bring it back to life which gives you more points.  This game is very easy to find cheap.
