Starting in the Modern Era, producing Goods changes: instead of being made solely from Coins and Supplies, Goods from the Modern Era and beyond are refined using two different Goods from earlier eras. These older Goods serve as the raw materials needed to produce Goods from the Modern Era and above ––they are now considered unrefined Goods. The Goods Deposits that boost production also come from these earlier eras.
Each era follows this pattern, refining Goods from two previous eras. For example:
Once you reach the Modern Era, most Great Buildings and Special Buildings will begin producing unrefined Goods instead of current-era Goods, providing twice the amount needed for refining.
