A strange little side quest
Between one round of Sandbox Universe and the next, this is worth knowing: Humans did not see the Moon's far side until a Soviet spacecraft flew past it in 1959. That old idea kept changing rather than disappearing. The Oregon Trail mixed travel, supplies, risk and survival decisions decades before resource-management systems became common in mainstream games. That long chain of experiments is part of why space still feels fresh when a game finds the right twist.
