Battle Realms follows the basic formula for many real-time strategy games. All of its factions have similar buildings with similar uses and workers. However, unlike in most real-time strategy games, the peasant worker unit is not just used for resource gathering and construction, but also for training into military units. Thus, military buildings in Battle Realms are not used for making units, but for transforming and upgrading them. Peasants gather the two resources in the game: rice and water. They also round up horses, which can be used to enhance military units in the game and can be outfitted as pack horses for peasants. Only one type of builder unit is required.
