I had created a thread earlier here regarding an expansion of the city radius. The city radius values found in the game databases are actually hardcoded, and hence there is nothing that we can do about this until the DLL is released "in a few months" (or whenever). However, it was hinted to me that one could force a plot outside of the city radius to be worked by means of LUA. I would like to know how that could be done and how to create a UI so that the human player will be able to assign their citizens to work tiles beyond the city radius.
