I will start the fort off, 2 year turns sound Kay? No mods, but I will probably use a texture pack and Dwarf Therapist.
Dwarf Therapist isn't up to date yet I think, but two year turns? I think that would be fine. Texture pack is fine too. I use mayday, but as I said, LNP will let you change the pack used by a save game pretty easily. Ah wait I'm wrong. DFhack isn't up to date, therapist appears to be fine, but unstable.
I'm currently dicking around on the Fallout mod for Dorf Fort, I made a small thing, it has a longhouse that' packed with beds, there's 10 beds in there. It's a one room longhouse. There's a dining area, a storage cellar, a kitchen/butcher's area, and a quarry. Most of its above ground.
Above ground is tricky, but not unpossible. Not even hard really, it just takes time.
Ok, it's up, check the rec room.
