HypersomniacLive: While you're bothered by those thinking that other (entertainment) media are inferior to books, you don't seem to abstain from this practice yourself (only into the opposite direction).
There is no comparison to be made between books, motion films, video games, etc. Each one offers a unique, personal experience (that the others can't offer), the value of which is highly subjective. One can enjoy all of them, but prefer one over others because they value more the experience one particular medium offers them.
Yup, every medium has its own purposes and methods in fulfilling those purposes. For an example, look at Rule of Rose. As a game, it's just plain awful. Even if the gameplay was decent (instead of totally broken), it still wouldn't be a very good game.
As a movie, on the other hand, we wouldn't have any of the tedium of gameplay, and we would be allowed to focus on the story and surrealism of that world.
As a book, we still would be spared the tedium of gameplay, but some of the surrealism would be lost simply due to lack of visual representation. There's a big difference in describing stuff (such as the imps that run around, the jilted motions and behaviors of the children, and the appearance of the general environment) and seeing it. Descriptions tend to lack the atmosphere that can be achieved from visual immersion. However, a book format would give us access to the direct thoughts of the characters, adding an extra layer of depth to the world and characters as we discover the mechanics behind the way these children and Jennifer act, interact, or fail to do either. In addition, symbols are much easier to see as such in books, as visually seeing an object tends to draw people's attention away from its possible symbolism.
In the case of Rule of Rose, film and book formats would be equal representations, though they would focus on and emphasize different aspects.
*note that I'm not saying video games are inferior (just that Rule of Rose wasn't ever designed to make a good one)
