You're thinking from the point of view from an experienced player here. Now, I do agree that toady should not spend time on documenting things or making the UI better until after V1 comes out (we can figure that out ourselves if we need to), but some apparently think differently.
Maybe I'm a little strange, but I didn't have nearly as much trouble as people seem to keep claiming they have with undestanding how the game works. I didn't even really have patience for a tutorial, I just went to the wiki, and looked things up for three days, and I was ready to start my first fortress, which I managed to get up to having the queen arrive, and building a major waterworks, all on my first try.
The game is really not that hard, and is actually a little too shallow for my tastes (which is why people spend so much time doing "stupid dwarf tricks" and other megaprojects), and I hope some more serious depth gets added soon.
Hell, most of the resource dependencies are, if anything, too simplified to be considered "intuitive".
This thread is, in fact, pretty demonstrative of what sort of "problem" causes many of these "make it friendlier to newbies" threads: The OP, after seeing a post in the forum, where a person used "*****" instead of tildes simply because he didn't want to go out of his way to copy-paste the actual double-tilde symbol (which is entirely reasonable), decides to make this post about how difficult that is to understand,
only to take that back when he was told it was actually the double-tildes that the game consistantly uses to represent water. This was something he would have figured out if he had looked in the game itself, or if he had read the wiki before posting. Instead he made a post about how hard it is for newbies, again, only to take it back when he had realized his mistake, and yet
there are still people going on about how hard this is to understand. (I'd like to take the time out to say that I don't mean to direct undue hard feelings towards Hammurabi if this sounds harsh towards him/her, since he/she was at least adult enough to recognize and correct the mistake he/she made.)
This only proves how it is the knee-jerk reaction of apparently quite a few posters here to just post complaints about things in the suggestions forum the instant they don't understand something because they can't be bothered to even try looking it up. This sort of thing can happen no matter
how simplified and user-friendly you make an interface, you're still going to get these knee-jerk complaints.
