Since the release of GURPS Dungeon Fantasy Adventures 1, there have been some calls for more GURPS Dungeon Fantasy adventures. There are three that I know of off-hand.
Recently two posters over at the SJG forums wrote up (or started to write up) introductory/one-shot adventures for GURPS DF.
First (and not yet complete at the moment) is the beginner's adventure by Stripe:
[DF] Shadowyrm -- One-Shot Beginner Adventure
Default [DF] One shot- Crevan Brokenhands Last Rest by Ego Archive
And we can't forget Beneath Castle Everglory, the as-yet incomplete but quite useful free DF dungeon. It's discussed fairly extensively here if you prefer some designer's notes.
