Goodbye Galaxy
From KeenWiki
Goodbye Galaxy (officially written as Goodbye, Galaxy!) is the name given to the second installment of the Commander Keen series. It consists of:
Because of the similarities between the engines (they are almost identical), Keen 6: Aliens Ate My Babysitter is often included as part of the Goodbye Galaxy "trilogy", particularly with Goodbye Galaxy modding tools which can often edit Keen 6 as well.
In the storyline though, Aliens Ate My Babysitter sits well and truly after the Goodbye Galaxy series, although some elements of the Goodbye Galaxy story do continue on in Aliens.
The Invasion of the Vorticons series precedes Goodbye Galaxy, however Keen Dreams is often considered to fit in between these two series, look and feel can be seen as being something of a halfway point between them, particularly in its introduction of the isometric style of platforms. (see Invasion of the Vorticons for more on this.)
