[suggestion] Excess resources? Global Merchant!
I find myself often with a huge abundance of a single resource and I have no idea what to do with it. None of the opponents usually want them, typically they have more than they need themselves.
It would be nice if I could cash them in for something else. Maybe have a global merchant or something. I wouldn't care if he ripped me off or not, but it would be nice if I could get rid of them for a few gildar. Perhaps the value of the resource could be based off how common it is in the world? And maybe this merchant could even give me some magic weapons or something if I give him a huge quantity of certain resources/gold?
