I dislike the idea of buying goods from a npc. This stuff should come from somewhere. We will already have the system set up to add these other resources, so why not use it? Once people get used to our trading system, I believe they will start to like it, or atleast be willing to work with it.
Also, if we can make the trading system affect the regional stats (etc), rather than just gold, I think it would cause some people to be more willing to try it. I may be wrong though.
