Every time you create a world in Dwarf Fortress you can give the world some depth by generating a prescribed amount of history.
Is there any good resource or explanation of what happens during history generation?
Does the game do a complete simulation of the lives and activities of all the dwarves/elves/goblins of the world? Somehow I doubt it. I imagine something more like a random number of births and deaths are generated for each day and after your 250 years (or whatever) the resultant number of creatures need homes, so fortresses and roads are built to match their numbers.
What kind of information is out there about what happens during this simulation-only time in Dwarf Fortress? Is there any mod that lets me see what happened during history generation more closely?
