I have composed a very basic mod (first in a series of modular add-ons that I have planned), which adds Hobbits as a playable race in both Fortress and Adventurer mode.

As if I have to describe them, Hobbits are less stout and sturdy than dwarves, but roughly the same size. They have no need for steel manufacturing, but are masters of farming and brewing. They do not use large swords, halberds, pikes, bows, or crossbows, but use slings better than any other race. They are notorious for their cultivation of hempen-weed for both clothing, food and ... well, pipe use.

Give them a spin and see what you think. Let me know of any problems. I am aware that their language file is not complete (using Human for now, and some of the hobbity symbols aren't in there, that is planned to be fixed as soon as I have a spare day to hobbit language formation). Other than that, they should work great. Please give me feedback on both Fortress mode (either playing them or just trading with them) and Adventurer mode if you can.
