In this paper, we discuss a part of participatory culture that so far has not received much attention in the academic world; it is the writing and reading of game fan fiction. The focus in this paper is on fan fiction, based on three different games that represent three different game genres: Tetris, StarCraft and Dreamfall: The Longest Journey. The aim is to advance our understanding of how players experience and understand the game environment, and promote further research interest in fan fiction based on computer games. We do this by discussing narrative elements in the above mentioned computer games, and the fan fiction that is based on them.
