Somewhat off topic (if there is a topic), but I don't see why companies even bother with licensing properties. The temporary boost in sales doesn't seem worth the cost of:

The only two motivations I can see are a) being REQUIRED to license someone else's work because yours is uncannily similar, and b) loving a work so much that you HAVE to play in their universe. A game set in the universe next door (i.e. a popular work with the serial numbers filed off) seems far safer and more secure. D&D and its imitators have elves, dwarves, and orcs but (after the hobbit and ent mistake) don't owe the Tolkien estate (or WotC) a dime.
