I love world building.
Creating logic where there would be none
should be a national sport imho.
Maybe it already is.

However, the funniest (and perhaps most useful)
resource I've been directed after sharing my
love for the stuff has been an article on 
creating sewage systems. Hydraulic goodiness!
But.. But.. I've never been writer-blocked
that way before? *dead*

I cannot be as detailed as some.
But screw expectations, worlds are
ever evolving in and outside of notice.
I'm detailed enough for fun
and that's all that's needed *o*

Uh, okay. On second thought, 
maybe this is a thread for group players.
I would thus agree on being intimidated by
non-fantasy worlds. What are the offerings otherwise?
Unless you mean fantasy that's more focused.
Ie, creatures, weapons, monsters of the week, etc.

Aside from the easy adaptation thing, which @lucius outlined 
rather brilliantly above- I'd say yes, it is indeed
about how easily the ideas are understood, what they can take,
breed, etc. Do you have a more concrete example
of what you perceive or have found to be a more difficult
integration into the wider audience?

In all's honesty, I don't think about liking a world 
or not. It's more about how the characters interact and
or what happens within it. Not leaving out of course,
what I can do with it *_*
