Salem

I don't know if it's been posted but I'd be very interested in there being a map layer for mines that's as big as the world map and would be able to dig around until you hit someone else's mine shafts.

Perhaps a couple of layers to separate the purity levels or something (sulphur - sulphers, mercury - mercury mines etc)

If you were determined it could be a hilarious new raiding game.

Yes, would love to see this. I love that mining system in HnH.

However, when I saw the title, I was "what does smuggling slaves to freedom have to do with Salem?" http://en.wikipedia.org/wiki/Underground_Railroad

Agreed. The mining/spelunking/building underground and caves stuff in Haven makes for entire other layer of strategy and stuff to explore. I know they plan on adding other metals but unless it's done similar to Haven it will always be just...blah.
