I have a nomination for the Hall, an
Epic Adventure at the Dawn of Time. The idea, according to the author, is to
"Gen a new HUGE world, and start playing from YEAR ONE. That would mean super low population. Super High Titan and mega beast population. And it would mean each Dwarf is "the first of their kind" No kids yet, no epic warriors, no time for anything. So EVERYTHING is new and from scratch." It is the story of not one but many dwarves, and follows their quest as they attempt to found a fortress at the dawn of the world.
The quest has been divided into two parts. The first uses adventure mode to create unique dwarves and bring them to the mountain home. It is a community story, and players take turns creating a character and trying to bring them to the designated spot halfway across the world. Most try and fail, but a few succeed. Both the failures and triumphs are recorded on the thread linked above, or you can read the journeys so far in
this PDF. 6 of the 7 necessary to found a fortress have been gathered, and the last will soon begin.
The second part, set to begin as soon as 7 have made it, will record their attempt to found a fortress at the dawn of time, and I look forward to their further adventures. The thread has been going on for almost a year, and I don't expect it to be finished any time soon! But what has transpired so far is enough for a recommendation to the hall.
(As a side note, I know dwarf fortress is not fleshed out enough for this to happen logistically. When the fort is founded, 7 new dwarves will be introduced into the game. But game mechanics are advanced enough so that the original 7 will eventually immigrate in to the fortress with their history intact. It might take several years, but eventually the original 7 will be gathered again.)
