Dwarf Fortress' seemingly never-ending development means more brilliant patch notes.
Dwarf Fortress is one of the most ambitious, complex world simulations ever crafted - and it can be a nightmare to play (be sure to check out Dan Pearson's feature, , to find out why).
The game has a tendency to... do its own thing. Once, for example, it started inexplicably killing cats. (Chris Bratt - remember him? - did a whole episode of Here's A thing on that very subject, and it's in the video below.)
