Best economic leader

Like a Cultural Victory, an Economic Victory relies on diversification. With all of that Gold, you can buy more potent military units, speed up construction, and expand your empire tenfold. For that, you want to select Amina in Civilization VII. The Warrior Queen of Zazzau’s name suggests she’s more militaristic, and to some extent she is with her +1 Combat Strength boon, but the money and resources pulled in per turn tip the scales.
+1 Resource Capacity for all Cities
+1 Gold Per Age for every Resource assigned to a City
+1 Combat Strength for all Units in Plains and Deserts
As you can see, Amina’s bonuses are all straightforward, plus-one boons that ensure, as the game goes on, that you grow in strength and riches. If you choose a strategic location for your empire, namely in the flat Plains, you’ll find your military units unstoppable. Should you lose any of your forces, the additional Gold allows you to immediately purchase replacements, sending in the reinforcements.
