(Sorry about my crappy english) Hello there, im not realy sure if there is already a topic about this, please let me know if it is. Im no moder, i dont have the slightest idea of how to make mods or custom content for simcity, so here is a request for the people who can make it happen. Having a Global Market with fixed rates is dull, it makes a trading specialized city completely useless unless you get your own resources from the ground, wich even if i did extract them it would take all the space i have reserved for RCI zoning. So..... is there a way to make the Single Player Global Market rates change randomly every once in a while? Making it change within a 3 day range would be just great, that way my trading cities would actually make a profit.
