Well, now that we are all settled on the previous and slight discriminatory discussion, I would like to ask about something silly, but that made me curious all the same:
Yes, food. Generally, all fantasy worlds have their own typically made up foods and drinks, so just imagine the troubles over something like chocolate would entail? They cannot mass produce anything, so if a country have the control over something that the others don't, they would get the attention and the prestige over the said product.
Now, why did I ask about this? Oh well, it was mentioned that the Amazons have a very delicious wine, I imagined that their kind of wine would grow only in Amazon lands. It would be interesting to see in future games simple references over the commerce or how people appreciated and enjoyed something simple. In a world building point-of-view, it's nice to know what the population enjoyed and lacked.
Commoner1: Man, I love this peace treaty with the elves and the "Amadons".
Commoner2: You mean the AMAZONS!
Commoner1: Yeah, whatever. I love this peace, 'cause now I can have my wine without paying the smugglers so much.
Commoner2: I don't know, my pal told me another day how they made poisoned wine especially for men!
Commoner2: Dude, you're crazy. I don't care, gotta enjoy my wine, regardless of what you think.
This kind of conversation over silly things might help a bit in the world building, at least, that's is what I believe.
