See, I had a funny idea in the opposite direction - a pack where you can't find ores or anything, but you start off with a couple of machines, and you have to basically retrieve scrap metals from places/mobs you raid, a bit Mad Max; you throw the alloys and stuff through a pulveriser to shred them down, then separate out the metals into their pure forms to effectively recycle them into other stuff. It was an idea, not sure if it would work, but it did intrigue me.
