So perhaps all the formerly useless ore of various kinds we used to find in Oblivion mines will finally be raised to a higher purpose.
In other words, we'll be able to turn Goblins into weapons and armor? That's apparently the main "product" of most mines in OB.
It would be nice to be able to smith your own equipment, especially if it's not done to one extreme or the other:
On the one hand, being able to craft equipment that's still not available in the game world because it hasn't magically appeared when you last levelled up.
On the other hand, not being able to craft weapons and armor until 6 levels after every routine bandit in the game has already discarded theirs in favor of something better.
This has the potential to become something really interesting, or it could be like FO3's funky "schematic" system where you collect a bunch of junk, click a button, and it swaps some of that junk for something totally bizarre. I'm definitely hoping for a more "craftsman" feel to it, not an "instant magic with a hammer and anvil" approach.
