Direct references to literature, whether subtle or obvious.
Part of the effort to split Genius Bonus. IMPORTANT: Should this only be shout outs, or count if themes and plots are also used? Any simple Shout Out to Literature, whether the work being referenced is well known or obscure, and whether the reference is subtle or openly states what it is. This is one of the oldest forms of media in history, and one of the richest. Whether poetry, novels, biographies, etc., they have had a huge influence on all fiction. Thus works in other media, or even other works of literature, will give nods.
