The Diffrence of Platform

In the world of digital media texts and para texts can easily switch places. Sometimes what is considered the main text can become overshadowed by its subsequent para texts, or in another case the para text becomes stand alone.  In the case of trailers, posters, and intro scenes this is not an issue, the respective para text leads to the viewers increased knowledge about the parent text. The para text is usually intended to interest audiences, but now since there are so many para texts, viewers have a sense of affinity with the text without viewing it. In video games this line between text and para text is even more gray.  Movies , Posters, Trailers, and Title sequences all exist in one medium. Video games however are produced on different platforms for different audiences.  Assassins Creed, a popular video game, has a very detailed narrative. This narrative has spawned many para texts, including short you tube videos, and other video games.  This is the link to the trailer for the iPhone assassins creed game. http://www.youtube.com/watch?v=-Nhmj-Gn7_w  

This iPhone game/app was created after the assassins creed series was in full swing, but what is its purpose?  Was it supposed to draw players of the original assassins creed game into a new text, or was it supposed to be a way for players to be drawn to the series. The level of intricacy varies between platforms. The iPhone version is much less complex and relies heavily on the original game for narrative support. But the game has decent graphics, solid game play, and could possibly stand alone.  In our exploration of video games as a para text of film, narrative superiority is becoming a much harder to discern.
