So, we have subregions for town now, super awesome! However, I think that we need to have more per level of town. As is, you currently get less regions per player as you progress. There will always be one per person based off of the minimum, but after that you are screwed.
With the way subregions work, you have to region doors in/out of your town, any gates, and any plots for users. This takes away from the plots meant for players, not to mention that people will want to region other areas for public use.
I think you should get 1/2 the amount of the max citizens.
