Adventure
Adventure games are characterized by exploration, puzzle solving character interaction & emphasis on narrative. Games belonging in this genre have fantasy, horror, mystery as well as comic elements in them.
The standard adventure games died out when 2D was replaced by 3D. Today, most adventure games are a mix of a number of genres. For examples, Prince Of Persia: the sands of time is a mix of action & adventure elements, with a third person view.
There are exceptions, though. Games such as Myst continued to be popular even in the 3D era. But the fact remains that adventure games are no longer major players in the gaming industry.
