Of course, to provide for balance, the areas near to the player will have the same type and quantity of resources so that both players will be in the same starting scenario.
That brings up another interesting thought. What if resources are not created equal. For instance, a robotic force would have little use for wood, but and Elf race would. (not that I'm planning Robots and Elves:) Each race or key might have their own strewngths and weaknesses. And perhaps portions of the maps could be dynamic. For instance, Instead of a map editor identifying that Crystal is found here, and Oil is found here, etc... perhaps it could just identify that this is a Resource spot, and when the map is generated, it automatically fills in appropriate resources for the base/race near by.
