It might be a good idea to mention that your embark started in DF version 0.40.24 (released in January 7, 2015) when you post about stress, because my embarks in 0.47.04 seem to be a much different experience than you had. I'm just a little concerned that others who didn't see when you mentioned 0.40.24 will get the wrong idea about stress balance in the current version 0.47.04. There seems to be less need for adjusting PERSONALITY:STRESS_VULNERABILITY in 0.47.04. Thanks in advance!
Good point. I made embark in 0.47.04 and after 5 years the largest embark zone's bug killed its play-ability. I did not provide any sleeping rooms and just basic Dwarven alcohols. Still, despite rain, I had not a single depressed Dwarf. Toady supposedly made test and run fortress with 20 types of booze for 5 years with not a single depressed Dwarf until sieges arrived with dead bodies and gore.
However, this old embark was already played for 5 game-years on 0.40.24. I played on 0.47.04 this embark then for additional 27 game-years. This is not covered even by Toady's tests. Majority of mechanics are working. I copied raws from 0.47.04 into my save and tweaked them, so I have functional library for example with 2 books so far and 1 copy and Dwarves keep reading those just fine. Guildhalls are working also as advertised for socializing. Still all 271 Dwarves are vastly affected in personality changes almost exclusively by rain. Maybe this rain issue has been addressed in last 5 years of DF development, but then why it still affecting my old embark, when I play it on 0.47.04? A rain is a rain, right?
I am sure some new players' embarks will have lots of noob issues, which will cause even more stress on Dwarves, then some stress relieving features missing from this old embark. Won't you agree? That is, specially if they keep playing it and playing it for a long time.
