My 1 cent worth. If it were not for the no resource gathering on the main map, I would just as soon not have a wilds. Our main map is large enough and our active players so few, that I don't see why we can't at least mine there for resources. No surface mining and no clearing of growth without replanting should be a given. I don't make massive builds, so I don't get resources preparing for them. I hate having to cart resources from the wilds to the main map, so I usually end up just building mostly in the wilds.
