to "MOTW", Internet fans invented acronyms such as "UST", meaning "unresolved sexual tension", and "COTR", standing for "conversation on the rock"—referencing a popular scene in the third-season episode "Quagmire"—to aid in their discussions of the agents' relationship, which was itself identified as the "MSR". The producers did not endorse some fans' readings, according to a study on the subject: "Not content to allow Shippers to perceive what they wish, Carter has consistently reassured NoRomos [those against the idea of a Mulder/Scully romance] that theirs is the preferred reading. This allows him the plausible deniability to credit the show's success to his original plan even though many watched in anticipation of a romance, thanks, in part, to his strategic polysemy. He can deny that these fans had reason to do so, however, since he has repeatedly stated that a romance was not and would never be." The Scully-obsessed writer in Carter's 1999 episode "Milagro" was read by some as his alter ego, realizing that by this point "she has fallen for Mulder despite his authorial intent". The writers sometimes paid tribute to the more visible fans by naming minor characters after them. The best example is Leyla Harrison. Played by Jolie Jenkins and introduced in the eighth-season episode "Alone", Harrison, was created and named in memory of an Internet fan and prolific writer of fan fiction of the same name, who died of cancer on February 10, 2001. Merchandise The X-Files spawned an industry of spin-off products. In 2004, U.S.-based Topps Comics, and most recently DC Comics imprint Wildstorm, launched a new series of licensed tie-in comics. During the series run, the Fox Broadcasting Company published the official The X-Files Magazine. The X-Files Collectible Card Game was released in 1996, and an expansion set was released in 1997. The X-Files has inspired four video games. In 1997, Fox Interactive released The X-Files: Unrestricted Access, a game-style database for Windows and Mac, which allowed users access to every case file. In 1998, The X-Files Game was released for the PC and Macintosh and a year later for the PlayStation. This game is set within the timeline of the second or third season and follows an Agent Craig Willmore in his search for the missing Mulder and Scully. Then, in 2004, The X-Files: Resist or Serve was released. The game is a survival-horror game released for the PlayStation 2 and is an original
