Marc Miller's Traveller (1996–1998), often referred to as T4, was published by Imperium Games after GDW dissolved and the rights to Traveller reverted to Marc Miller, the creator of the original game.
It returned to a heavily modified version of the original rules and was set in the early days of the Third Imperium (Milieu 0). This edition is currently available on Marc Miller's website. Miller has stated that T4 was "plagued by rush," explaining that the books were released without enough editing. He also stated that in spite of the quality issues that resulted from this, he does not believe that T4 is the least popular or most controversial edition of the game.
