Understanding resources: food, wood, stone and gold

Throneweld uses four stored resources. FOOD supports growth and troop training. WOOD is a core construction material. STONE becomes important for fortifications, advanced structures, units and research. GOLD funds advanced development and military activity. Production continues in real time while you are away, but stops at the kingdom storage cap. Upgrade Farms, Lumberyards and Quarries, watch the resource bar, and spend before a resource remains capped. Inventory resource crates are useful reserves, but opening one never pushes a resource beyond current storage capacity.
