Rhialto the Marvelous
SOC-13
I listed all those I could think of as likely candidates. Feel free to mention others.
I liked Martin's Homecoming when I read it, but as yet have not got a chance to run it.
Issue #5 : Day of the Gathering
For a one-night adventure I would add Ordeal by Eshaar.
Totally forgot about [Ordeal by Eshaar]. It's actually my one-shot favorite. Exotic locale, strange aliens, diplomatic backstabbing, what's not to like?
Those are all real good choices - Kinunir is a Traveller classic, Nomads is Dune on a water world, Arrival:Vengeance is a great tour of the Imperium on an iconic ship, the Traveller Adventure is the classic campaign.
I'm surprised that the Shadows/Research Station Gamma/Twilight's Peak isn't listed. I think that is where my vote goes.
