Interesting stories can provide a useful framework for inspiration, setting goals, or looking at what "rule sets" are in play.
If it's intended to be a "simulate (a substantial part of) everything" game, the above stories suggest game elements such as different depths of snow, non-hostile wild animal interactions, animal pathing behavior in snow, tracks, and animal habits/routines.
Dwarf Fortress has for a long time used short stories to describe interesting interactions that the developers like, and then tried to add features to the game until similar events can just happen naturally.
Thanks for answering this to me. This is what I have in mind basically. I'm also working on something like Dwarf Fortress but a "lite" version which is more accessible.
