The initial gold amount is randomly calculated, primarily based on the number of cities a Civ starts the scenario with. Additionally, "major combatants" receive a much larger amount (again, based on city count) than minor combatants or city states/non-playable Civs.

The amounts are further refined to provide a wide range of possible gold awarded. Some games will be significantly more generous than others - in an attempt to provide some varieties in playing the same Civ more than once.

What kind of gold award changes were you thinking about? Need to know this to determine the best way to recommend a fix. Thanks.
