Space Quest 1: The Sarien Encounter

Players of the original game are never told the hero's name, but are instead asked to enter their own. The default name of "Roger Wilco" - a reference to the abbreviated radio communication, "Roger, Will Comply" - became the de facto name of the hero in the later games of the series.

Space Quest was eventually remade using Sierra's newer SCI language, which allowed the game to upgrade from its original EGA graphics to VGA. This version was released on August 20, 1991; in addition to the new VGA graphics, which were drawn in 50's B-movie style, it now featured digitized sounds. The game's interface was also changed, with text-entry being replaced by a standard icon interface which would be used by many SCI games. Curiously, the VGA remake featured the taste and smell icons, which were rarely used during gameplay and were only featured in one Sierra game after Space Quest, namely Space Quest IV, where they were as rarely used.

Adventure Comics (a division of Malibu Graphics Publishing Group) released three issues in 1992 of a comic based on Space Quest under the name The Adventures of Roger Wilco. The first was written by John Shaw and was in full colour. The other two were written by Paul O'Connor and were black and white. The print run was very small and the books are very hard to find now.
