only one need (food), and no wants. Settlers in produce buildings have wants under two headings (prosperity and decoration), and as the city grows, they acquire increasingly diversified needs. If the player doesn't ensure a settler's needs are met, that settler will eventually go on strike. In Paths to a Kingdom, how the player interacts with buildings is substantially different from any previous title in the series. Work yards cannot be built directly, but must be attached to a base building. Each base building can have three work yards attached (depending on the availability of space), and each base has specific yards which cannot be attached to other buildings. The rate of work yards can be modified by controlling the distribution of food. Although some work yards don't require food, the player is free to send both "plain food" (fish and bread) and "fancy food" (sausages) to the base buildings, with plain food doubling production and fancy food tripling it. Work yards which do require food can be supplied with fancy food, which will double production. Military In the first four titles, the player's territory can only be expanded by building a military complex near the territory border and having at least one soldier stationed within, or by conquering an enemy complex. In The Settlers and The Settlers II, soldiers are automatically created from the pool of existing settlers as needed. In The Settlers III and The Settlers IV, the player must manually recruit soldiers by building a barracks, with each individual soldier requiring their requisite weapon to transition from settler to soldier. In Heritage of Kings, military recruitment is substantially different than previous titles. When the player recruits a soldier, that soldier is automatically a captain, and, provided there are sufficient resources, a set number of soldiers are simultaneously recruited and assigned to that captain. Once a captain has soldiers assigned, and at least one of those soldiers remains alive, he is invulnerable in battle. When all soldiers within his group have been killed, a captain can return to the vicinity of the barracks, where the player can recruit replacement units without the need to recruit another captain. In Rise of an Empire, similarly to the first four titles, the player's territory can only be expanded by building an outpost in unoccupied territory. Soldiers can only be recruited in groups of six at a time, meaning the player cannot
