I've been playing the same dwarf fortress world for a couple weeks now, about 20 years in the game, and have recently begun keeping a play log as I went. After a while I decided that it would be fun to start writing journals from character's point of views similar to the excellent Bravemule story. Where this was a shared world, with several fortresses already haven risen and died in this period of time it got me thinking that the easiest way to track all of the disparate information for story-writing purposes would be to create a wiki so I could easily cross-reference characters, relationships, deities, artifacts and so on.
Obviously it's a bit lacking in detail early on in the world's history due to me not keeping any actual records for a while and having to rely on the in-game legends mode, gamelog and seperate save files, but I plan on being much more meticulous as this goes on, including images of the fortress, and character profiles of the dwarves living in my fortress.
I'm currently deployed to Afghanistan with the Canadian army, so I've been doing this in my off-time at night to amuse myself, satisfy my OCD/ADD (I try to do everything in exact detail but tend to get distracted by those details), give myself something to think about at the gym and exercise my creative writing.
Again the site is kind of patchwork at the moment, I only started it about 2 hours ago after all, but I have uploaded my main play log, some fight details, and began cataloguing artifacts, important historical figures and civilizations. Eventual plans are to use all of that to create some fun journals, stories or art inspired by the game history, and you are more than welcome to do the same.
Let me know what you think, or any suggestions/help you might have.
