[DF] How Much Setting Information Do You Like?

[DAT]

The ‘Cool Backstory Syndrome’ thread (http://forums.sjgames.com/showthread.php?t=69296) over in the ‘Roleplaying in General’ forum, started me wondering…
1) As a GM of your own DF game, how much setting / background / backstory do you develop?
2) As a GM of a published DF game, how much setting / background / backstory would you want?
3) As a player in a DF game, how much do you care to read / listen to if you are making your own character?
4) As a player of a pre-gen character in a DF game, how much do you care to read / listen to?

I been in games were the starting description was something along the lines of:
The adventure starts in a standard D&D setting (faux-medieval European), and your characters are 100 yards outside the gate of the frontier town of Dodgeburg … what do you do?

And at the other extreme, 15-20 pages of general background for players to read plus 2-5 pages of personnel background knowledge (separate from the page or two of player generated backstory).
