I'd like to get some community opinion and feedback on the set 6093 Flying Ninja Fortress.

http://www.brickset.com/detail/?set=6093-1
At 694 pieces (many of them very unique) and 9 minifigures (including the wobbley-armed skeleton), this set was quite large.
Being modular in design it was one of the easiest official sets to re-arrange or add additional copies of this set (or others) to expand.
Released in 1998 and part of a new direction from LEGO, the Ninja series was part of the Castle theme group, but explored other historical parts of the world in Asia.
The world of the Samurai, ninja assassins and lawless robbers may not seem very "Castle" to some, but the fortress was indeed a Castle.
This theme expansion brought gunpowder and katana swords together in some pretty epic sets.
What did you love/hate about it? Do you have one or are you hunting it down?
Share your memories, treasure hunt and experience with this set please.
