I think there are new genres out there in the 'unexplored'. It is the same with each new technology.

In the beginning people try to translate the success of the old media into the new media, and often there is disappointment about all what is not working as good as in the old technology. Like all these games that follow the AAA movies (matrix, harry potter ...).
Usually it takes some time to discover that on the other side there are unique possibilities, that are the real strong features of a new media.
Look at the early days of movie making. In the beginning movies where silent, like a book, that was transposed into pictures. It took years until they discovered the power of sound to transport moods, feelings etc. Today we have digital effects, that bring people to the movies just to see these effects (matrix, transformers).
Or take the history of books itself. In the early days they were just used to keep in a written format, what were the common stories of a society (Ilias, Odysee or Thora, Bible and Koran). It needed (centuries and) courageous individuals like Michel de Montaigne to write down personal stories and publish them. Today we have a hugh market of all kinds of literature.
Who knows what possibilities are waiting out there in the interactive world of computer games?
