Its just a game and as most posted its a supply and demand and also in my case being impatient to build something. I rarely trade for gold but I browse the market and use both the german and tradesim sites to see their trade calculator and go by that. I myself at times will pay a really high price for something because I dont want to wait for the time to produce it or because of my work schedule I want that item now and not later. SO the markets going to be what it is because of those 3 main factors. TIME+SUPPLY+DEMAND.
