Your fort sounds just like Bastiongate, but with fewer dwarves and more FPS. What have you accomplished?
Not a lot. I've walled in all of the caverns, although I have cavern 2 open all the time now specifically to invite forgotten beasts to visit. That cavern gets no wildlife anymore, since I released some plump helmet people into a pit to try to breed them. They didn't breed, and when I dumped a couple of tame rattlesnakes in with them, the snakes indeed killed most of them, but apparently came to a truce with the final 5. I assume that when the last one dies of total boredom cavern 2 will begin generating wildlife again, but I'm in no hurry to accelerate that anymore.
We get regular goblin sieges, but no necromancers. It's not an evil biome so there's little danger from wildlife.
I have no great aspirations for the fort. It is no-migration, so the entire fort is descended from the original 7 settlers. I used the family affairs dfhack script to forcibly marry 6 of the beginning 7 so that I would actually get kiddos. The first ~20 years were kind of hardscrabble, with a lot of careful task management required to make sure plants were harvested timely and cooked food was removed from the kitchen. It is far less labor-intensive now that I have a good number of working adults. All I really want to do is see how long I can run it - and how long I can run it with a FPS above 20. It's been dipping into the teens lately, which makes me extremely impatient with it when I have to give it actual attention. I've been on an animal-reduction spree, which means giving away the low-value animals. I don't want to slaughter them, because their low-value meat is not wanted.
My only real goal is that I want my dwarves to eat well and drink well - no sewer brew served here, and it annoyed me greatly when some crundle burgers wound up in the food supply. I do everything I can to minimize low-value food. I want them to be dressed well - all stanky goblin underwear goes into the magma chute. Everyone gets masterwork furniture. There's a lovely statue garden and zoo. It's a relatively small fort, physically.
1. Only 12 FBs in 45 years!?! I've had hundreds in the same amount of time! How big is your world?
It is a medium-sized world, and I embarked on year 2 (the years I give are post-embark - the actual year right now is 47). When I peeked at Legends, there are boatloads of forgotten beasts in the world. They just don't feel like visiting through the 2nd cavern level I suppose.
I've also seen only 1 titan. Most of my visitors have been semi- and megabeasts, which fell straight into my trapline with little hassle.
3. Relax, the seeds will just get dumped out on the ground (or in the barrel) and your dwarves will stick them in a new bag.
Awesome. Thanks!
2. Go ahead and try breeding those minotaurs, I'd like to see what happens. I've got some ettins and giants I can breed and I want to see if it works before I try it.
I haven't decided for sure yet. I'm still thinking about how I want to do it, and I periodically haul out one of the minotaurs to be bait in my silk farm, and I don't want to disrupt that.
