"Alpha Centauri" set out to capture the whole sweep of humanity's future, including technology, futuristic warfare, social and economic development, the future of the human condition, spirituality, and philosophy. Reynolds also said that "getting philosophy into the game" was one of the attractions of the game. Believing good science fiction thrives on constraint, the developers began with near-future technologies. As they proceeded into the future, they tried to present a coherent, logical, and detailed picture of future developments in physics, biology, information technology, economics, society, government, and philosophy. Alien ecologies and mysterious intelligences were incorporated into "Alpha Centauri" as external "natural forces" intended to serve as flywheels for the backstory and a catalyst for many player intelligences. Chris Pine, creator of the in-game map of Planet, strove to make Planet look like a real planet, which resulted in evidence of tectonic action. Another concern was that Planet matched the story, which resulted in the fungus being connected across continents, as it is supposed to be a gigantic neural network.
