Paper topic: looking at a game as literature

I plan to analyze Braid in my final paper.  I had a hard time thinking of games as literature before playing Braid, so I am intrigued by how it creates a fictional world and a coherent narrative.   Marie-Laure Ryan puts forth some ideas in “Toward an Interactive Narratology” that will be useful in my analysis, along with several other sources.  It is remarkable how Braid plays with time and represents the complexities of human emotion.  One may fairly ask whether the author could have told this story as effectively using another method or technology, and I hope to address that question.
