One idea I was having is it would have been nice if some, if not all, resources were "produced and stored".
By that, I mean, like every turn you work an oil well, you get 1(or some number) unit/s of oil.
Then, oil would be consumed every time you produced one of those units that needed it.
It would be nice if a system was made that oil was consumed when you moved or fought with those units, but that is more complex and harder to balance, perhaps.
Regardless, a system of building up storage of resources would've been nice, so you could trade resources in quantity, you could build up strategic reserves, and the trading of resources would be more significant and more nuanced... nations with multiple oil wells could truly become oil nations, as it is, if you have one well you are set. There is no supply and demand.
How it could work for wonders is you assign your resource to be funneled to them, and say 1 unit of copper lasts for 50-100 hammers of production for the Colossus.... 6 units of copper total needed to build it at the hurried pace.
