Your population's happiness and productivity depend on meeting their needs. Early on, Farmers require Fish and Work Clothes. As they upgrade to Workers, they'll demand Schnapps and Sausages. Each population tier has unique needs, which unlock new buildings and production chains. Keep an eye on the green and red icons above houses; green means needs are met, red means they are not. Unmet needs lead to lower happiness, reduced income, and potential riots.
