In this article I will have a look at how point&click interfaces work in the articulation of a game's story. First I will draw a distinction between three fundamental narrative layers. Then I will define the types of narrative articulation that an interface must support for a meaningful and compelling gameplay experience. Finally I will have a look at the game Diablo to describe in more detail how its point&click interface is utilized in achieving the construction of its story.
The Fundamental Layers of Narratives
We can distinguish three layers  that work together to build the structure of a narrative. These are:
In the video game, these layers are open to interference/alteration. What enables such interference is of course the ‘interface’, which is a set of input devices that re-configure a user as to identify with, and perform as, a fictional entity in a fictional universe. 
The Articulation of Narrative Elements via the Interface
An interface will enable the articulation of narrative elements that belong to the three layers mentioned above. In other words, we can speak of three types of narrative articulation that take place as we use the game interface.
As each three types of articulation take place as a result of player interference, the game narrative, which is the combined structure of Events, Actants and Narration, comes to life.
Blizzard's Diablo: Articulating Three Narrative Layers with One Click
Diablo is one of the best examples to illustrate the successful articulation of a game narrative via a point&click interface. In this game, only by clicking on the interface, a player puts all three types of narrative articulation simultaneously into motion. The result is one of the most addictive games that has ever been created. Using the cursor as the focal point around which all other game systems (such as the camera) are built, provides the player with extremely fluent gameplay that fosters a very strong narrative feel. Let’s have a look in detail at how it happens:
At the center of the game flow is the click. A click results in articulation on all three narrative layers:
As the player continues to interfere with the open work, gameplay builds the narrative.
In this article I tried to illustrate through the game Diablo how game narrative can be tied to a game interface in a simple yet striking way. The better we understand the role of particular player interferences in the articulation of narrative layers, the higher are our chances to provide gameplay with a strong feel of story progress.
 A fourth layer, which has been left out of the scope of this article, is the Narrative Situation. For a broader description of these layers, check out my earlier article "Four Categories of Interaction".
 We are speaking of ‘event’ here in a strictly narrative sense, as things that take place in a fictional universe. The narrative event (for example killing a monster) is, although both are obviously connected, not to be confused with the user event itself (like clicking on the interface). This would ignore the process of mediation and synchronization that takes place in order to immerse a being primarily external to the fictional game universe into a primarily fictional role within that game universe. Furthermore, the Events layer cannot be limited to events originating from player input since a variety of events are performed/simulated by the game system itself (like actions of NPCs).
 Again, we are not talking about real players/users but narrative entities whose actions and traits are narrated/mediated to us. An actant's presence is always a narrated one. Hence it is not identical with the real person that gives her input to decide the actions of that narrated presence. Besides, user input is only one of the many ingredients that are used by the game engine to construct the actants presence. Also, games feature many actants which are not controlled by the player but the game system.
 An interface isn’t simply the extension of a real person. The role of the interface is to re-configure and synchronize our real presence with an in-game presence that is designed to possess the qualities that drive the plot forward. This is crucial in creating a feel of immediacy between, and identification with, the actant's role that we will perform in the game world.
 The definition of character as a 'paradigm of traits' has been put forward by the American narratologist Seymour Chatman.
