I didn't want to start a whole new thread for this, and since it comes from the same source, this seems a likely place for it.
This is one of the most useful and complete checklists for world building concepts that I've ever seen, and I've looked at a few.
http://www.sfwa.org/2009/08/fantasy-worldbuilding-questions/There's quite a bit of repetition as you go through the various sections, but logically so, and it's very easy to spot the bits you've already read and skip them.
And to me, from my story's perspective, I don't necessarily have to answer each and every one of them, but its still great to be able to say "nope, that one's not important", rather than wonder if I'm missing anything.
If there's another good place for world building info, please feel free to point me, or to copy this in, or what have you.
I'd give this one four stars and call it highly recommended.
