The five main resources

Wood, Stone, Crystal, Food and Gold are the five primary resource types. Building projects, units and research interact with different supplies. The Town Hall does not remove scarcity from the world.

Wood and Food draw from renewable local stocks. Stone and Crystal rely on finite local reserves. Gold can come through the game economy and the Grand Market's bounded civic activity. Workers and appropriate buildings are used for gathering; obtaining a resource at one island does not mean that every other island has unlimited supply.

Review your stock, local site availability and building costs before a large project. Use storage wisely and remember that different worlds keep independent inventories and progress.
