Re: General suggestions for the future update, global trade...
Troy, I am afraid you are correct and that why I mentioned we will never see the most ideal supply and demand driven trading in this game, but I do wish out of suggestions there floating around that at least they would consider to add filter on number of the same items to be displayed at any given time. And Sheppard I definitely agree with your point that what we get to buy in GT is what others are selling, but judging from my experience what you see is driven by your level, and definitely we see only a fraction at a time of what is actually offered. It seams as it goes through cycles, one week half of the items are burgers, another lamps, right now I am stuck with bunch of wood and steal. As for income, there is definitely some fractional formula I understand it wont give one coin per citizen, but at least it would make sense if I get 20K for one million citizens I should get 40K for 2mil, and not just 3-4K more, makes no sense.
I like your idea of transforming from one building to another, at least between those that already require specialty items, but we know that's not gonna happen 🙂 The answer there will be bulldoze and build a new one
