Space Quest

Space Quest is a series of six comedy sci-fi adventure games created for Sierra On-Line between 1986 and 1995. Each game followed the adventures of Roger Wilco, a janitor who has a habit of being in the wrong place at the wrong time, which usually ends up in him saving the universe.

Official Games

Space Quest I

Space Quest: The Sarien Encounter was originally released using 16-colour EGA graphics in October 1986. The game was created using Sierra's Adventure Game Interpreter (AGI) engine which combined 2D graphics with a text parser.

The game was later remade using 256-colour VGA graphics and re-released in August 1991 under the title Space Quest I: Roger Wilco in the Sarien Encounter. This later version was created using Sierra's Creative Interpreter (SCI) and featured a fully graphical point-and-click interface with no text parser.

Space Quest II

Space Quest II: Vohaul's Revenge was released in November 1987 and used the same AGI engine that was originally used in the first game. Technically it performed exactly the same as the first game, using a combination of 2D graphics and a text parser interface.

Space Quest III

Space Quest III: The Pirates of Pestulon was released in March 1989. This was the first Space Quest game to use the SCI engine, which was still an early version using 16-colour graphics at the time. Whilst it still retained a text parser, it was also the first game in the series to allow movement commands to be issued with the mouse.

Space Quest IV

Space Quest IV: Roger Wilco and the Time Rippers was released in March 1991. Using an updated version of the SCI engine, this was the first Space Quest game to use 256-colour graphics, and was also the first game in the series to completely abandon the text parser for a point-and-click approach. It was also one of the first video games ever to use motion capture animation. The CD-ROM version was released in December 1992, becoming the first Space Quest game to feature full speech.

Space Quest V

Space Quest V: The Next Mutation was released in February 1993. It was the first and only game in the series not to be developed in-house by Sierra On-line, and was instead developed by their sister company Dynamix. It was also the first and only game in the series to be sponsored by an external company. The telecommunications company Sprint Nextel sponsored the game, and their logo appeared in the game in numerous locations. The game used the same SCI engine used in the fourth game, however it did not feature full speech. The game was controlled by a point-and-click interface identical to the fourth game.

Space Quest 6

Space Quest 6: The Spinal Frontier was released in 1995 and used the last official game to be released in the series. It used the final version of the SCI engine which allowed Super VGA graphics with 256 colours at 640×480 resolution, and featured full speech. A revamped version of the point-and-click interface used in the last two games was used to control this one.

Space Quest VII

A seventh game, Space Quest VII: Return to Roman Numerals, was planned and development begun in 1996. A trailer for the game was released with The Space Quest Collection. However, poor sales of Grim Fandango lead to many companies dropping adventure games in favour of more popular genres, and Space Quest VII was cancelled when Vivendi Games took over Sierra. The project was restarted in 1999, and again in 2002 by Escape Factory, however neither attempt to revive the series got very far.
