Civilization level and gnome's mood

[Bounty]

How it works? I've read it depends on amount of buildings but I would like to know more. Is the civilization level affecting gnome's mood as well?

Hey there,
the civilization level does affect the mood. It is determined by the freetime buildings you have built and maybe more. We have a more detailed thread here somewhere on this forum. I know that luxury buildings will raise the expectations of your gnomes. Some people experienced less stressed wiggles while playing the campaign with medieval buildings only.

I have every freetime building now, yet they'are still stressed. I think that's the reason why I never completed this game when I was younger
