Pitfall II: Lost Caverns for the Atari 2600 was one of the greatest games made for that system. It had great gameplay and interesting setting. It also had one of the best instruction manuals ever put to paper at the time. It was told in Diary format, with very little breaking of the fourth wall that to this day I still find very endearing.
This was the Lost Caverns print advert that ran in the United Kingdom in the 1980s. With its stylized art and movie poster-like structure, I think it is superior to most of the ads that ran in the United States. Great ad for a great game.
