ordering the construction of a building), with the AI handling the delegation of orders to specific settlers. A major change to the mechanics in The Settlers III is that players do not have to construct a road network. Instead, settlers can walk freely around the player's territory, with the AI handling pathfinding. Players can also build marketplaces, which allow for the establishment of trade routes between areas on the same geographical region, and shipyards, which allow for the manufacture of both transport ships and trade ships. Races and economy In the original game, the player could choose one of three races; Romans, Egyptians and Asians. Quest of the Amazons added the Amazons as a fourth race. Unlike in previous Settlers titles, each race has a slightly different economic model. For example, the Romans' and Amazons' construction industries require roughly equal amounts of wood and stone, the Egyptians' requires more stone than wood, and the Asians' more wood than stone. Each race also has specific skills. A new feature of The Settlers III is "Divine Intervention", whereby each race can call upon their deities for economic and/or military assistance. Once the player has both manna and priests, they have finite access to a number of spells, the nature of which depends on the race. These spells include tuning iron to gold, turning enemy soldiers to allies (Romans), turning fish to meat, starting forest fires (Egyptians), turning stone to iron, temporarily giving soldiers extra strength (Asians), turning gold to stone, and temporarily freezing enemies (Amazons). Military The player's territory can only be expanded by using pioneers or building a military complex near the territory border. Each complex must have at least one soldier garrisoned for the territory to expand. To recruit soldiers, the player must build a barracks, with each individual soldier requiring their requisite weapon to transition from settler to soldier. The player can also build lookout towers, which are manned by regular settlers, and which can see for great distances, but don't grant new territory. There are three classes of soldier: swordsmen, bowmen, and spearmen. The strength of each recruited unit depends on the level of "Divine Promotion" which that class has reached, with each class requiring two promotions to reach the maximum level. Each race can also produce war machines; catapults for the Romans, ballistae for the Egyptians, cannons for the Asians, and war gongs for the Amazons. Upon
