About the next turn: I would be ok with both options. A new fortress could be refreshing, but I'm starting to get attached to the current monstrosity. Also, for me the fortress is still playable without issues.
I had promised a short summary of my fortress experience.
Imgur uploads are currently not working for me, so this is without pictures, will add them later. First runIn my first (failed) run I tried to make everybody a legendary swimmer, like applet did. It was horrible. I actually used the existing cistern, dug a room with food and booze adjacent to that, and broke down the wall, allowing the water to rush in. It was quick to set up, but had horrible results. I found out at this point that dwarves just dehydrate and starve in water, so I had to temporarily get everybody out for sleep/eat/drink sessions, then had to herd everyone back in by digging another adjacent room and repeating the process. The fortress turned into a cratered muddy landscape.
I also found out that dwarves were very creative in escaping from a swimming pool. They climbed up wells, escaped through locked doors, scaled impossible walls etc etc. It all spiraled out of control and ended with the water turning red from blood, after someone snapped. It is a good thing this alternative reality no longer exists.
Second runFor my second run I went for pump operator skill for everybody instead.
Except for the kids, they would get their swimming pool. (I don't know how else to train them).
I started by expelling the two long term visitors. one of them had a kid, so three dwarves left. (the visitors would not count for the score according to the rules, but were counting towards the 100 dwarf limit) I expected them to be replaced with migrants pretty soon, but migrants never came this year, so this was a mistake.
The pumps were set up in the trade depot area. The depot was demolished,
and I did not bother to replace it. The pump room is now the guild hall for the mighty pump operators guild.
Some say the poor dwarves in this room had to endure slave labour with no real purpose or goal, or tangible result. They were however far better off than the children and the couple of dwarves that I had been unable to separate from these children. They were guided into a small (7x5) food and booze stockpile, with a couple of grates in the roof, and some plumbing. The room could be filled with a screw pump from the cistern. It was important for the operator to close the pump in time, else the children would drown. Luckily we had a lot of pump experts, so this never resulted in tragedy. Using another pump the room could be drained without opening any doors. Once the level of the water had receded enough, the children would drink from the muddy water and eat from the soggy food. Some children would even fall asleep in the half flooded room before new water rushed in, the sign that the next training phase would start. It took almost an entire year. The doors were only opened in the midst of winter, when all were legendary swimmers, and when I imagine, the water had become uncomfortably cold. One of the adults refused to leave the room, he just stood there, frozen in the door opening and died of dehydration several days later ( I swear he had not yet snapped or gone mad). He was my only casualty, bringing the number of dwarves to 96.
One of the larger issues I had was that at some time Spriggans started to actively sabotage my fort (the dwarf Spriggans, not the forum member)
He made demands for large gems and other near impossible to obtain stuff, and would drag my pump operators to prison if they did not deliver. The sentences were ridiculous too, and it looked like a number of dwarves would be unable to complete training. I decided to fire the sherrif and hammerer, and deconstructed all cells. I have disregarded all mandates since. Reinstating justice will likely come at a price.
Another player dwarf, Radipon, was also not cooperating and ended up being the only dwarf without legendary skill.
There were a number of forgotten beasts in the cavern, and they might still be there. I had it walled of the whole time. There was one dwarf with a mood who created a grate, if I recall correctly, but without gaining skill. No other noteworthy events.
The turkey rooms are the only other thing I've added to the fortress..
