@IBZFanatic While your OP said fair trades you didn't specify trade ratios so when I read it I assumed players would still be choosing the ratios as we do now. People in thie game have slightly different views of what fair trade is, some put it down to simple cost, if it costs twice as much then you should get twice the amount for it IE 4 Ebony for 8 Lumber. Others want to factor in the size of the building and would find a 1:1 trade ratio between Tar and Coffee unfair as the Tar producer has to use up more town space to build his building than the Coffee producer does. So my point here is "fair trade" means different things to different people.
With strict age limited ratios it would limit the ability to exploit this feature, takes away the freedom to value certain goods more than others but it does restrict exploits.
+1 for the resticted G to G trade system.
Ahhh, I understand your initial concern. That makes clear sense. Of course, as you agreed, with a true fair trade ratio across the ages, a treasury "exchange" could only be a win-win for all players/guilds involved in GVG.
