CIVILIZATION can be won six ways:
CONQUEST — be the last civ standing. DIASPORA — settle Alpha Centauri and keep the colony supplied. THE DOME — finish all five components. SCORE — lead the world in 2100. PAX MERCATORIA — own the world's economy. CULTURAL ASCENDANCY — be the most admired. See its own page.
If the signal is answered, 2100 is not the end. What follows is not written here.
CONQUEST outlasts every rival.
DIASPORA: launching is not arriving, and arriving is not winning. A ship in flight dies with its home city; the colony must then be supplied 20 years by a city with MISSION CONTROL. Lose it and the count begins again.
PAX MERCATORIA: 2.5 times the next economy for 75 turns at Prince, with Banking, three rivals standing, no war of your starting, and half the world bound to you.
THE DOME: all five parts, standing anywhere in the world.
