Here is an outline for an alternate Traveller setting. In this Universe, the Soviet Union wins the Cold War. The Villani then conquer and Earth that's stuck at TL 7. The Soviet Union surrenders without a fight, and in return for tribute, the Villani allow the Soviets to continue governing Earth. The Soviets act as obediant vassals until they've copied sufficient Villani technology, and then they stage a second communist revolution through propaganda and subversion. Imprisoning and the assasinating the entire Imperial Family, and so instead of establishing the Ramshackle Empire they establish an Interstellar Workers State or the Union of Socialist Stellar Republics. Technology is somewhat uneven in this setting. The maximum working tech level is 12, and everyone is guaranteed employment by the state, and not only that, but all of the starships are owned by the state as well. All forms of employment are illegal except by the state, and all of the Stellar Republics have the same government type, a Self-Perpetuating Oligarchy based on the socialist model. Factories typically emply thousands of workers, evem on frontier worlds. Although much of this work could be automated, its not as the government has to employ everybody. Robots are not employed except in hostile environments where humans cannot operate. The USSR operates on ten-year-plans, typically quotas are set to determine how many products will need to be produced over the next ten years. Innovation is discouraged as new technologies tend to threaten jobs and are deemed not useful in the governments efforts to employ everyone, the bog exception of course is the Military. Other nations that existed in the OTU also exist here with the major exception being the Imperium. The Zhodani are considered to be the class enemy of all socialist peoples, mostly because two of them can communicate within the USSR and not be overheard by the Committee For State Security, a spy organization that spies on much of the citizenry.
