a developer would probably give you the same answer as Lightbringer did. they are doing what they promised, they are working with modules, even adapting the modules to make it more enjoyable. while the original plan was to introduce economy in the beta, they are working on implementing it in town square. this shows us that the developers do listen to the community and try to adapt. it was long before said that the module wouldn't be grand like light pointed out and just because its small now doesnt mean that it wont be finished.
I understand that you are frustrated by the time it is taking but don't lose hope, the developers are still working on the game and they want this to be completed just as much as any one of us does.
