Here's my impression: those brewing stones are overkill.
Let me get a better understanding of the situation, you locked yourself into permanent sieges right and the caravans never come while the enemies still do right? I suggest modding the stone reaction at the altar from using gold to steel since you get steel from sieger's corpses and they are of equal value. If all else fail, consider making a mist generator.
So, all exports I could provide were bone crafts and occasional corkscrew.
Um, how about goblinite? If you have survived until year 8 then you definitely would have gotten at least high master smith immigrants in all fields to reforge them into highly valuable stuff. Striking magma (I guess you already have) allow you to cast obsidians if you need stones. Due to a bug, magma creatures wont ever bother you unless you happen to stumble right next to them.
Also, you seem to have taken out the yarn cloth, but moods still can request it. (.23 version)
Wha, I'd do something about this. If you have a screenshot of his demand I'd appreciate.
When I'm at it, I'd say something about the animal revision I'm working on:
1) Make zones less bland by removing redundants (i.e. Lots of 1 clustered fishs) and by filling in new creatures (i.e. peguins for glaciers)
2) Make the distinction between major biomes more clear. If you embark on a savage biome, savage creatures will be much more likely to show up and if it's an evil biome, seeing normal creatures would be a very rare event. Similarly, creatures that live in cavern level 1 and 2 will be more likely to show up on cavern level 1 then 2 and if you play with only 1 cavern level it'd be cavern level 2.8 for the most part.
2.5) Optionally: Make all underground creatures non-undeadable to prevent miasma spam. Seriously, I really hate that miasma stuff.
3) Tweak some creatures abit to make them more interesting or replace them with prehistoric creatures. Hopefully prologue will publish some that I can steal so I dont have to make all of those dinos.
Right now I'm (still) working on cataloging animals (at work) but deadline for a new release is still today so I gotta work hard at it
