Marc Miller's Traveller (T4)
After GDW closed its doors, Marc Miller -- who is to Traveller as Gygax was to D&D -- secured the rights to the game system. He authorized this ill-fated rewrite of Traveller by Imperium games (also known as 4th Edition Traveller). During its two year run, the company published two dozen books, detailing "Milieu 0." Many players felt that Traveller had gotten out of control, and away from its roots during the MegaTraveller and Traveller: The New Era phases. Milieu 0 takes play back to the founding of the Third Imperium, a time of rebuilding after "The Long Night."
T4 was poorly received for several reasons. The first strike was the anemic state the RPG industry had fallen at the time, with declining sales and the shake-up that had claimed GDW and others in the last half of the 1990s. By 2000, Wizards of the Coast and Steve Jackson Games would emerge as industry survivors with their flagship D&D D20 and GURPS systems, respectively.
T4 - Core Rulebook 
A surprising highlight of the rulebook is all the interior Larry Elmore sketches.

Milieu 0 (Campaign) 
Milieu 0 actually comes in two distinct versions: An earlier softcover, and a deluxe hardcover compilation adding 4 new chapers, and incorporating previously published First Survey.
"Traveller's campaign world is revealed! The Long Night, a period in which the remnants of a once-mighty interstellar empire regressed to barbarism, has passed. Starships once again ply the space lanes, and civilizations are reawakened to the vast interstellar community of worlds. One ambitious world has designs on empire itself, and the growth of the Sylean Empire is in full swing. It is the time of the pocket empires, despots and philosophers, merchant princes and piratical tyrants, an age when the foundations of the next thousand years of history is being laid. Milieu 0, the dawn of empire is at hand!
Milieu 0 Campaign opens the era of Traveller play, showing the referee how to begin and maintain an epic game where his players can ride the waves of unfolding history."
First Survey 
"With the establishment of the Third Imperium, the strong economic forces that created it continued their work by driving an outward expansion by the Imperium into neighboring worlds. This survey book is intended to serve two distinct purposes: a reference work and as an adventuring log."
Contains Traveller UWP information for nine sectors, backdated to the Year 0.
