In addition to scientific advances, the designers speculated on the future development of human society. The designers allow the player to decide on a whole series of value choices and choose a "ruthless", "moderate", or "idealistic" stance. Reynolds said the designers don't promote a single "right" answer, instead giving each value choice positive and negative consequences. This design was intended to force the player to "think" and make the game "addictive". He also commented that "Alpha Centauri"s fictional nature allowed them to draw their characters "a lot more sharply and distinctly than the natural blurring and greyness of history".
