In the 10 years since the term was coined 'design fiction' has become an increasingly common approach in HCI research. The practice involves working with 'diegetic prototypes', that is prototypes that need not exist in reality, but instead exist from within a 'story world'. Although fictional aspects are not unusual in HCI prototyping methods (e.g. storyboards, personas, Wizard-of-Oz), the breadth and flexibility of design fiction poses new challenges. This paper originally featured quotes from peer reviews of design fiction orientated papers that have previously been submitted to ACM SIGCHI conferences in order to highlight inherent challenges when reviewing research that may be based upon or include elements of fiction. In response to the SIGCHI Executive Committee's request to not directly quote reviewers the quotes have now been redacted. This somewhat changes the paper's tone and also makes very clear that publishing discussions relating to peer reviews (or the reviews themselves) is extremely challenging.
