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.

The games in the series are:

• Space Quest: The Sarien Encounter was released in 1986. The game was later remade using VGA graphics and rereleased in 1991.
• Space Quest II: Vohaul's Revenge was released in 1987.
• Space Quest III: The Pirates of Pestulon was released in 1989.
• Space Quest IV: Roger Wilco and the Time Rippers was released in 1991. This was the first Space Quest game abandon the text interface in trade for a point-and-click approach. The CD-ROM version was released in late 1992 and was the first Space Quest game to feature full speech.
• Space Quest V: The Next Mutation was released in 1993.
• Space Quest 6: The Spinal Frontier was released in 1995.

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.
