So I was playing last night and noticed that my hearthlings were having to walk fairly long distances to gather Iron and I got an idea. I’m kind of taking this from minecraft, but it would be awesome to be able to build a railcart system to quickly transport goods or hearthlings from a mine/ forest/ or farm to a central point in your town. Expanding onto multiplayer, it would be even more awesome to implement a rail line between towns for easier means of trade.
And also, to add a level of difficulty, maybe the goblins could breach or ambush rail cars, creating a new set of challenges for someone if they choose to have a rail line to a mine half way across the map.
