It's a 0.47.05 vanilla (with DFHack) 5x5 embark with a stream, lots of trees, and parts of it are rejuvenating revolting reanimating. Some pics were posted earlier in this thread, the round walled castle with weird towers. No drawbridges for safety allowed, only doors and traps.
I'm using it as a learning exercise for FPS preservation. Not a lot of hope based on stuff I've read, but what the heck, I gotta learn for myself.
No petitions for guildhalls were accepted until the 21st year, now we've done two halls because they won't stop requesting them. It didn't seem to hurt their happiness too much. Gave them all a bed and cabinet in cramped common rooms up until about year 20 and now have the 60-odd regular military in spacious individual tower rooms. Slowly working on getting the civilians better quarters. So far I've only had to send 1 unhappy soul on a suicide mission (got captured by goblins) and 1 other took a walk off the plank into a 20z cavern pit.
Other than that, after all this time almost all adults are armed with steel and have been in squads long enough that only training 3 months/year has them legendary, then they train only 1 or 2 months. So I'm letting them all wander the 1st and now 2nd caverns, cleaning up the corpses and fighting the reanimated dead as they go. A few are getting pretty stressed, but those get taken off duty and mostly recover. My focus now is finishing 2nd cavern cleanup and there are still TONS of corpses to dump-smash... 20 years of forgotten beasts slaughtering everything makes a mess.
I've had no werebeasts yet and wonder if it's because my start year was 5.
With DFHack I've just been using cleanowned to send worn clothing to the traders, and recently fix/drop webs, lastly fix/dead-units to get the migrants coming.
