My previous post was vague and though some of that was intended to promote comment and discussion, I feel I may have been unintentionally cryptic in both the post itself and my comments. It was not my aim to imply any order of worth to each of the forms of media mentioned, and I also feel it was remiss of me to not mention some other forms.
Since I made my initial post Corvus Elrod has presented his own take on my position which is at once divergent from my own and highly interesting in its own right.
As for the comments , I thank you all for adding you voice to the discussion. A few people seemed to have seen the direction in which I was going, most specifically moromete, SR, and Roger Travis.
Dan Bruno and Chris brought up something I found quite amusing, they mentioned how sports games in particular are representations of the sports themselves. This is true, but the sports they represent are games, and the explorative nature is true of the game itself and therefore true of the virtual recreation of the game.
That covered, I now offer an elaboration and clarification of my original post.
The defining feature of any media, any art form, is the means by which it communicates meaning.
A work of literature can represent an idea or concept, it can even explore that idea from several different and conflicting perspectives. In addition we can explore the work by researching the life of the author and the cultural and historical context in which it was written. Literature has the capacity to present representations and allow exploration. These elements are its function, they are what it does. This is separate from its form, separate from its means of communicating meaning
All works of literature regardless of purpose or quality use written language to communicate their intent. The method by which they represent, or allow exploration, is by describing concepts and events through the medium of the written word. Their form is descriptive.
The function of music is often the same as that of literature, to communicate a particular concept or idea; even if that idea is as straightforward as evoking joy. Through the selection of particular notes, and melodies, played with particular instruments music can express complex ideas and evoke powerful emotions through association and allusion. The form of music is expressive.
Much of what is true for literature and music is also true for other media, other art forms. Their function is to communicate meaning and this can be done through representation or exploration. External to the works themselves the manner in which we approach them can be an exploration. The differences between literature, music, film and games is the form they take. The means by which their function is realised.
Film uses a combination of many different elements to create a representation of an idea or event. Dialogue, action, set design, lighting, cinematography these are just a selection of aspects of film. They combine to create a portrayal of an event that communicates meaning. However realistic or plausible the event is, and even if the footage is of an actual event, the choices made regarding editing and musical accompaniment transform it from an actual event to a subjective representation of an event. The form of film is representative.
Like film, games use a combination of different elements to create a representation of an idea or event. Unlike film they allow interaction with that event, they allow you to potentially change the outcome of that event, thereby altering the context and the meaning that might be communicated. They allow an exploration of possibilities within a bounded context. Games are systems of rules, when we play we are exploring the possibilities that exist within the logical and physical world defined by those rules. The form of games is explorative.
The central concept of both The Art of War and Rome: Total War is an examination the different levels of military strategy. The former is a work of literature, the means by which it communicates its intent is through description of certain tenants of warfare. The latter is a game, the means by which it communicates its intent is by providing you with agency within a simulated environment. You are given the means to explore the effects of your choices and to develop strategies and gain an understanding of the underlying tenants of successfully waging war.
A particular concept or theme is not exclusively tied to presentation in one form. Honor is not a concept that can only be portrayed by literature. Each medium uses a different form to present its central theme, its core idea.
That is a fundamental difference. The same concepts and themes can be examined by any and all media but the manner in which they are presented, the form they take, is inherently different. This difference in form leads to different aspects being highlighted or given prominence in different media. The rules and traditional that are applicable for one form of media do not always translate to another form.
