* CreatorsApathy: Richard Moe got a case of this near the end of ''Airport's'' development, which is the reason Level 99 of Lost Luggage is UnwinnableByDesign.
* DummiedOut: Each game has unused content that can be found in the game files, and certain clickpoints and alterations to the dialogue can be accessed by messing with the INI files.
* TechnologyMarchesOn: Many airplanes featured in ''The Airport'' are long gone from airlines. Also, airports have vastly evolved since the game's initial release; the security is much different, for example.
* WorkingTitle: For a very long time, the series was going to be named "Junior Encyclopedias: The [Location]", and a version of ''The Farm'' actually was released under this name. It was eventually changed to ''Junior Field Trips'', and the official game titles were changed to ''Let's Explore the [Location]''. ''Farm'' got an updated version that reflected this, which is the one most people are familiar with.
