Game: Reunion

In the 27th century, centuries of peace have allowed great scientific progress in the development of the first interstellar warp drive. Two research ships, designated Explorer-1 and Explorer-2, are outfitted with the experimental drives and sent to find new planets of colonization. Only Explorer-2 returns back to Earth out of the 2 Explorers. Refitted as a colony vessel, the Explorer-2 is once again ready to embark when, suddenly, peace is disrupted and the humans were ripped apart from each other. At this same time, a planet-wide rebellion stages a great coup and overthrows the Earthen government, throwing the world into chaos and severing the union. The Explorer-2, crewed by a loyalist space crew, barely escapes the rebellion and leaves the Solar System. Years later after the rebellion, the Explorer-2 arrives damaged at its destination and a colony is set up, naming it "New Earth". After many generations of being separated from Earth, the colony is self-sufficient enough to develop a mission only the best can tread: Explore nearby space, research new technologies, harvest resources, develop a space fleet and eventually... reconquer and reunify Earth, leading to the greatest reunion the universe has ever set its eyes on.
