Quest I and II were developed in Adventure Game Interpreter, Sierra's own programming language. Space Quest III was written in Sierra's Creative Interpreter (SCI), which had 3-D capabilities. Space Quest IV marked an evolution in terms of graphics by increasing the number of colors from 16 to 256. Roger Wilco Roger Wilco is a fictional character and the protagonist of the Space Quest series, introduced in Space Quest: The Sarien Encounter in 1986. Roger is depicted as a bumbling but well-meaning everyman character. He is a space faring janitor who has a tendency to attract trouble and stumble into dangerous or interesting situations. Despite saving the universe on multiple occasions, he seems unable to gain any respect from society, and works as some type of "sanitation engineer" throughout the series. The character's name is a reference to voice procedure, one of many puns in the series (it means "receiving you, will comply"). The first two Space Quest games allowed the player to choose the character's name, which defaulted to Roger Wilco if left blank. This feature was later removed in the remake of the first game. Roger is originally a janitor from the planet Xenon of the Earnon system. He is first introduced as the janitor and sole survivor of the scientific research ship Arcada, which was overrun by the apparently hostile Sariens. After several extremely deadly adventures and a bit of janitorial work, he enters the StarCon Academy. Graduating in Space Quest V, he is promoted from a janitor to captain of the garbage scow SCS Eureka. He also meets Beatrice Creakworm Wankmeister, with whom he becomes romantically involved. In Space Quest 6, his spot in the limelight ends as he is busted back down to janitor and assigned to the backwoods of the cosmos. According to Space Quest IV, Roger would eventually marry Beatrice and they would have a son (Roger Wilco Jr.) who would later travel back in time to save Roger's life. Beatrice is absent from Space Quest 6, but she is mentioned in the game's closing credits and by Roger himself. By the time of the fictional Space Quest XII, when Roger Jr. would be a young adult, Roger would be "unavailable" for some reason. The details are never disclosed. While Roger retains his basic appearance and sustains no lasting damage from his swashbuckling and repeated near-mutilations, his hair begins the series brown and changes
