Tried to set it up. Suprisingly, this is very prone to tantrum spiral:
Typically, it goes something like this:
Embark with 20 blocks, 20 logs, 2 barrels, 5 bags, 2ropes, 4 stones.
Build well, seed stockpile, walls, gather plants so that dwarves eat them and produce seeds, once enough seeds are accumulated, draft everyone but one to military and station inside, have one wall em up inside.
1st attempt:
Everything goes fine, except one carp-caused death them building well, but one dwarf was fairly unhappy and got even more unhappy though from drafting and from subsequent release, he started tantruming and killed dwarf, a lover of expedition leader.
Expedition leader got unhappy because of it, of course, having to endure decay of two dwarves as beng yelled at and recent draft. He started tantruming and startef fistfight. Cue in dwarf of other dwarves to make sure he behaves, his hammering and death.
Suprisingly, one of his friends got extatic because of this as he was ellected Expedition Leader, which did not last long because he fell to carp that came through fishing grate.
With only three left, all miserable, i gave up on this attempt when it started raining.
2nd attempt went similary:
In the end, only two dwarves were left: Extatic expedition leader (curiously, only expedition leaders died in this attempt, so each dwarf got his turn of being extatic, then yelled at a lot and killed by carp.). Luckily, inital cat couple bred like rabbits and subsequent carp attacks killed of kittens.
In the end, 6 farm tiles ended up being more than enough to feed dwarves, two types of food kept them stable ("ate decent meal recently"), well kept giving them happy thoughts, and generally with expection of 5 friends slowly rotting downstream, everything was just fine. Male kept getting flatterer skill, even. Same that female, expedition leader, kept mouring her lover/fishfood.
3rd attempt:
Planning building on top of cliff so that carp related deaths become thing of the past, wondering whether fishing will work across z-levels, the same way that well works.
