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.
I don't know if we could this. Have you seen how crazy it is out there in the wilds? I've gone to incredibly far distances to get away from the areas that have been caved to oblivion. AND I still find lit up caves. Its mind boggling to me.
Yeah, we're not going to go without a Wilds at any point in the near future. It's far too valuable. Plus, having a "free-for-all"-esque area helps from accidentally stepping on anybody's toes.
