Let me start by stating that this thread is in no way a complaint. I find the situation described amusing, and maybe a tiny bit frustrating, but it's more good than bad, for certain.
I'm currently playing with Civilization Forge 2.23. My current map has sand, a stream, and reasonably abundant vegetation, and it's a good biome, so some of those trees are the quite valuable Silverwood.
When I dug down, I noticed several good stones. Dolomite - magma-safe, and good for flux. Bituminous coal and lignite. Limonite.
And then I noticed some more of them.
And then I found more. Mostly dolomite, with veins of mostly coal, but still enough limonite to be quite content.
Then, as I was getting my magma works in place, I found some sphalerite, and lots of cassiterite.
I wound up with over 700 bars of tin and a decent amount of zinc. My military(small yet, but I'll probably add another squad with the next migrant wave) is wearing head-to-toe steel, with crucible steel warhammers.
And yet through all this I have yet to find much in the way of other metals. A goodly portion of galena, some garnierite - but precious little of the other base metals, or indeed reliable veins of precious metal. No aluminum, no platinum. No magnetite nodes, alas - that would have been a great thing to dig out for my vault; excavate an entire magnetite cluster, line the pocket with steel walls and a few steel supports, seal it with steel doors, the works. Anyway, I have enough limonite that that's not crippling. But aside from one vein of tetrahedrite, I haven't found any copper ore to speak of - yet piles and piles of metal for alloying it.
I usually find plenty of copper but none of the alloy metals. Ironically, CivForge turns the weighting of copper to additive in those alloys from 1:1 to I think 4:1... if I was finding copper, I could try to import tin and zinc, and run with it. But no. Tin, zinc, and more tin.
Ever feel like you're getting too much of a good thing?
