I need to squirrel myself away for a weekend and get stuck in. I know I'll love it because it's the kind of game I enjoy - the entry point feels a bit higher than I'd expected though!
Rock and stone! It got way easier for me, when I started to just rely on plump helmets. Dwarfs would eat them raw and drink them brewed. That got me over the first winters.
Out of curiosity, what do you mean by "dire pretenses"? I remember the steam release, but wasn't heavily into DF before that, so maybe I wasn't aware of things going on in the community? Or is that more about the state of the game on initial release?
