Rex Nebular and the Cosmic Gender Bender
Trivia
Audio Logs
In addition to the already humorous manual the game originally came with Rex's "voice-activated auto-transcribing audio log" (actually a transcript of said log). This 20-plus page fiction gave a deeper insight into Rex, and described the events that led him to Terra Androgena in much more detail that in the opening sequence.
Written by Steve Meretzky, the log was also pretty funny to read, with highlights like reading an entry where he goes on and on about how exited he is about his new log and how he's gonna make an entry every single day, only to read that his next entry is a year later and reads "what the hell is this piece of junk?
Bugs
The game is rather bugs-free, however there is a nasty one by the end of the game. Spoiler alert - when you make bombs make sure that you DO NOT make chicken bomb until the city is flooded. The game seems to check if you have "chicken" item in your inventory before you place the first bomb (timebomb) and "chicken bomb" will not count as such and the game will not let you continue.
If you had 4 megabyte (or more) memory in your PC, items in your inventory would spin instead of standing still.
Endings
There appears to be four (4) possible endings to Rex Nebular: - The "A Quick Death" ending - The "Honorable Death" ending - The "Victory!" ending, and - The "Decompression" ending
The First of Many!

MADS engine
Rex Nebular was prominently advertized as the first game to use the MADS engine (MicroProse Adventure Development System......SCUMM anyone?) used in other games like Dragonsphere.
