The aim of this study is to examine the relationship between author, text and user-generated modifications in the context of the computer game Civilization 4. These relationships are studied in part by analyzing how the game mechanics have been modified, and in part through analyzing the communication taking place between players of Civilization 4 in the CivFanatics online forums. The study concludes that fans as creators are increasingly leaning on each other and their self-produced accumulated body of knowledge in the generation of new and further changes to the narrative universe, and that the original creators of the game have all but faded from view. This suggests that fan creativity is not situated against or directed at particular authors (original or otherwise), but a community effort quite independent from original intent.
