So for base Dwarves/Elves/Humans I'm thinking of giving each a special workshop (eventually) that will help differentiate them a little.
Dwarves get the Stonesmith's Workshop, this is a workshop where a Stonesmith can carve stone into Stone Armor or Weapons, they're incredibly heavy, and the weapons are mostly good for bashing but not edged attacks or stabbing, but the armor will provide solid early protection for your dwarves. I'd like to make the Stone Weapons/Armor decorated if possible.
Elves get the Woodsmith's Workshop, similar to the Stonesmith but for Wood. Wooden armor is far from as effective but much lighter, Wooden weapons vary, decent for stabbing, not that great for edged or bashing attacks.
Humans get the Papermill/Scribe's Workshop. Papermill creates Paper from Wood Pulp and Water, then the Scribe's Workshop combines Leather, Paper, and Ink (TBD how to make this) to create Books which are a craft (or simply Paper/Ink to make Scrolls to avoid conflicts with current books.) Would like to make the books/scrolls "engraved" with images if possible.
Its worth noting some races might get one of these workshops as a second unique, so the Storm Dwarves also will get access to the Papermill/Scribe's Workshop, Wild Dwarves might also get a Woodsmith, etc.
