A while ago, but less died and more the equivalent of retired. Between unstoppable soldiers (honed by years of fighting god damn monstrosities and zombie hordes,) FPS steadily getting worse and worse, and players constantly being unable to either start or finish thier turns we decided to fold and bow the fort out of being played (after a nice bloody spring of the final turn of course.) We currently still use the thread for discussing aspects of the fort itself (stories, plotting what to jam into the sequel, modding opportunities, etc.)
Frankly the thread is such a mess I'll be impressed if anyone can organize it anymore at this point.
For example, I'd like to make heavy use of civilization forge elements, particularly xelics good and bad, sand raiders (renamed to Dune Wardens as they are separate from the sand raiders of Syrupleaf,) hobgoblins, and possibly the vamarii, add in various advanced weaponry which I dunno will even work properly, and at least one inherently deranged/incomprehensible race: Either the manamaids or Sequivets. To top it off, there's intent to include roving bands of spawn as 'wild animals,' possibly some crude form of making cyborgs out of injured dwarves, and megaspawn.
Of course the way things are going, a good bit of that may need to be phased out now just so we can survive the first year or two. FUN is all well and good, but it's less fun in the traditional sense if we get slapped with a total party kill multiple times in a row before we can even really get anything accomplished beyond "dig hole in dirt, hide like kobolds." Also next time around I plan on taking care of maintenance myself, because if nothing else I can maintain threads. I also would like to point out that the wiki should probably be rebuilt and the TVTropes page is painfully outdated (or was last time I looked at it.)
