The Forgotten is set in New Orleans (circa 1930), were you must find your friend, Richard Haliburton, who has mysteriously disappeared. He's been exploring a sect of black arts practitioners called Collectors.... are they somehow involved??
People have long (in the computing timescale) suggested that adventure games can be released in a serial manner, a chapter at a time. It is a bit different from releasing a complete game, then a sequel that continues the story. With this approach, each installment is small and dependent upon the rest of the series for its storyline. The advantage is that each individual chapter can be released relatively inexpensive. The Forgotten is a series that attempts to take advantage of this marketing strategy. The Forgotten: It Begins... is the first chapter.
