I have also spent time with Lynx at a close proximity, both times they purred and acted like a house cat. Before hissing and slowly walking away.
I'd also like to point out how great it is that we have such varied commenters here on HN. I checked in tonight to see what's new with the NSA/Apple/Snapchat/usual tech stories of the day, and instead I got this gem about the timber industry and wolves.
I'm sorry if I come across as stupid. I don't see the connection between these two assertions.
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.
