There are eight areas in which civilizations have natural strengths. Each strength gives a civilization one free Advance and one rules advantage as outlined below: Agricultural Agricultural city improvements (aqueduct, for instance) are easier to build, and the center city square and irrigated deserts produce one more food. Commercial The center city squares of all cities and metros produce extra commerce, and less corruption is experienced. Expansionist The civilization starts the game with a scout and can build more later, and passive minor barbarians are friendlier. Industrious Workers complete tasks faster and the center city square of all cities produces extra shields in cities and metros. Militaristic It is easier to build military improvements (barracks, for example), and combat experience is gained more quickly. (continued)
