I think EU2 should have some more resources. Here are some ideas :
-Diamonds (for South african provinces)
-Whale oil (for the Newfoundland and Labrador zones, northeast of america)
-Silver
-fruits (mediterranean and central american provinces, fruits, at that moment in history, were really expensive in countries that weren't growing them)
I also think that the provinces could produce more than one kind of ressources, something like 2 or 3 kinds.
Finally, I think that products that come from provinces where there is a manufactory should be "transformed", like sugar would become rum and iron would become arms.
