I consider myself a sort of intangible Doom-like figure. (In the senses of both the comic villain and the archaic use meaning "fate") I love my dwarves in DF, but not because I care for their hopes and their dreams. I love them because they're MINE.
I try to make them happy, but their desires only matter to a point. I'm truly sorry if your only goal in life is to be the best damned cheesemaker the Mountainhomes ever saw, MY fortress needs a moat, grab that extra pick and get to work!
This is distinctly different from the communal will of the fort (though I quite like that idea, as well as the dabbling possessive spirit one). I find that if I allow it, the communal will of the fort is "everybody party all the time and no work gets done", so the meeting hall table is mysteriously un-designated from time to time.
I used to think of myself as the leader of the fort, and name a dwarf after me as I've so often seen done in succession games, but I don't do that anymore. So many times, the "avatar" that I picked for myself tried to subvert my will.
We do have some operational parameters as players that are outside the functions of Dwarven Gods, so that title isn't accurate either. We can only be in one place at a time, and only range as far as the limits of a single fortress. So in that respect, we are less than gods. But then, we are greater than gods too, for we can create and destroy entire game worlds on a whim. Whatever we are, we are extremely powerful, but we can't subvert Free Will, and we have an extremely narrow focus.
This is a really interesting philosophical consideration. I highly approve of this topic, because I've never really given this much thought until now.
