How about this: New yields: Silver: Base: 1 -> 1, Improvement: 1 -> 1/ Bank: 1// -> 1/ Monopoly: +10% -> +10% Biggest buffs because I think it's the worst resource in the game right now. This improves the type and timing of yields, but doesn't add any. Citrus: Base: 1 -> 1/ A small bump. Tea: Improvement: 1/ -> 2 Monopoly: 10% -> 2 I really liked production Tea. This brings it back, and makes it more interesting. Only citrus actually adds more yields, in this case a single gold.
