This is my first fort that reaches the 4 year mark (not sure about this, since I can't figure out how to know for sure how old your fort is).
I had restarted every other one (about 8 of them, I think - only been playing for 2 weeks or so) either because I had too many people or because I got crushed by gobbos. For this one I decided to go along and have some !!FUN!! to the last dorf.
So, the story of the fort is: it has reached, on it's prime days, 70 or so dorfs. I got ambushed, and lost about 45 of them, I think. One of the gobbos killed like 30 or so o_O . For this first ambush I had to enlist almost every dorf to finish them off. My militarized ones got crushed, so I sent off some civilians afterwards, deciding to play along.
I was left with 13 dorfs. The attack and the tantruming dorfs really took their tolls.
I soon got some migrant waves, but also some 3-4 new ambushes. I defended them better this time, having parted my new military dorfs into 3 squads. That helps micromanage them, and the battles went better. I also received some pretty good fighters on the migrant waves.
I had no iron, so the only weapons I had were some silver blunt weapons, and some gobbo leftovers. I also had to trade for my armors. Luckily, one of the things I had learned on my previous abandoned forts is that a craftsdorf making stone crafts on "repeat" will soon create enough wealth for you to buy everything every merchant has to offer. That and my blooming gem industry.
(I mostly keep gems, though...).
That stonecrafter has gotten legendary +5 now, and when I tell him to craft on repeat I get flooded by "crafty has created a masterpiece" (or something, forgot the exact message) messages. Because of that guy, I have 3000+ food stores, and my cook spends his days turning all kinds of weird foreign foods into lavish meals for my hungry dorfs.
Now I have 4 squads training two of every three months, one of them being a 5-dorf archer squad.
Also, found the adamantite spiral. Working on extracting and smelting those now.
