Nearly every fantasy book I read that involves dwarves I think they must have ripped off DF, or the other way round.
I was reading a book called War of the Flowers which doesnt even have dwarves in, its mostly about fairies. There is a part where they encounter a tower with a long engraving spiralling around the outside. The main character asks someone what is depicted in the engraving and the answer he gets is "Oh, mostly goblins getting killed"
I had to check to see if it was written before 2006 is was so Dwarf Fortressy I thought it might be a sly reference!
