Genre: Video Game-Based Mystery
review in one breath
In terms of video/PC games, I generally prefer those which focus on heavily armored robots with heat-seeking missiles. There is, however (and amazingly enough), another, entirely different genre of game which involves you exploring every nook and cranny of an environment to discover clues (which generally lead to keys which help you unlock further clues) into some over-arching sinister mystery. In the West, games like Myst or Riven, or more recently Syberia are exemplars of this genre.
