Air Crash Investigation is a story about choice and replayability.
The player puts herself in the shoes of the flight investigator and
make a series of decisions, each branching into a segment or piece of
the story about different suspects, as well as the private life of
the investigator. Depending on the decisions made by the player, such
as accusations on suspects, the story turns out differently and reaches
a different ending.
The Patrol, on the other hand, is story much motivated by the development of
emotions through dialogues. The story focuses on a security guard on patrol
making conversations with his buddy, and these conversations would eventually
build up the emotions at various scenes, the relationships and profile of the
characters and shed light on the truth behind the story.
