My most recent OCD behavior was digging 4x4 squares of up/down staircases (aligned to the nearest map corner) either 4, 8, or 12 tiles in height. Why? So i could rebuild the floor and ceiling with a uniform rock type of constructed walls. Why? Because constructed walls totally block all cave-in effects. "But cave-ins don't happen as long as there's a tile connected orthogonally to support!" Yes,
i know.
Then, with the carved staircases still in place, i'd build those ceiling and floor walls (which forced me to continually expand to get walkable space) and then construct the actual side walls. All of it out of the rough stone that was mined, so if i changed my mind or needed a rough stone, it'd be easy and reversable; if i want a valuable room, i'll build it out of valuable metal bars. If i wanted art, i'd put in a dyed and decorated cloth rope "carpet" and statues. Once the area was finalized, the up/down staircases that remained were channeled from below, top to bottom so none remained.
Unless it was a totally mechanical or useless corridor (ore mineshafts) in which case i left the place alone and empty.
The highest anything got was 12z for the entrance. Normally, often used paths and rooms were 4 or 8 high, with an optional 4 high sewer beneath that often used pathway. Places that handled water would dump their used water into the sewer; fountains, waterfalls,
drowning chambers noble mandate processors. The sewer, being in effect a giant empty unpopulated room, was also the refuse pile.
Staircases were treated like they were ladders and not actual stairways. Ramps were used in both straight and spiral to move dwarves vertically; ramp incline did not exceed a 1:4 ratio.

And of course i'd dig down staircases onto the soil layer, then up staircases below them, then removing the non-border down staircases with a channel, then removing the up staircases without down staircases above them... [Then i'd do a ramp border along the remaining staircases so they didn't eat pathing cycles.] So the miner would be legendary before EVER touching stone because he altered each tile on each z-level two times. I needed every rough stone (and ore... and gem) i could get.
[Edit:]
- Starting 7 dwarves only. Every time.
- 4 female dwarves, 3 male dwarves. Every time.
- Absolutely no grudges between dwarves. Every time.
- Absolutely no barrels, bags, or any non-raw/non-consumable material/objects, because i HATE HATE HATE
(This Item Came From Outside The Fortress And Doesn't Contribute To Your Fortress Value) items.
- No contact with mountain home for 20 years. Every time. (FPS death before this though)
- [SPEED:1][NO_EAT][NO_DRINK][NO_SLEEP] for most of those 20 years. Every. Damn. Time.
I don't like to get things stuck in places where I can't retrieve them, even rocks. A rock dropped into some water drives me crazy, so whenever I make something involving water, I have a plan for emptying it.
This.
Damn PTSD flashbacks to 2D channels filled with stone. Ugly, ugly grey 'o' sitting in the middle of a field of blue. AARRGGHH
