Space Quest I: Roger Wilco in the Sarien Encounter is time sector caused by the affects of time travel on the Space Quest Universe. It is a Parallel universe that more or less replaced Space Quest I: The Sarien Encounter (original version) time sector in the memories of those who may have experienced both. This is the timeline that appears in Space Quest I: Roger Wilco in the Sarien Encounter, The Space Quest Companion (first and second editions), and The Official Guide To Roger Wilco's Space Adventures (with minor variations).
