Do you mean Fun, in the Dwarf Fortress sense? That sounds absolutely brutal.
Any challenge is fun. Absolutely bored of hero games where you do not even have to do anything, and it was a miracle to find this game and just as I thought I have lots of fun even now. Since the start of EA all I’ve seen point to a very fine complete game from a very fine studio. And that is fun too! Hell I’ll be damned if I miss out this one ;)
