These are articles that need some kind of citation, or source explanation. This should include page numbers, web sites, reference to an interview, and/or the individual making the claim (game designer, producer, Sierra Employee, etc.).

Its understood that some trivia may originate through unofficial means (I.E. fans contacting designers). Due to the nature of this kind of information, it may not be verifiable through published or web sources. So a reference to the person who gave the information is needed. King's Quest Omnipedia is not so formal to prevent behind the scenes information of this type, as long as source of the information is given.
