Genres defined by a break from realist, present-day setting: science fiction's technological or future premise, fantasy's invented or magical world, horror fiction's aim to frighten, gothic fiction's atmosphere of decay and dread, and utopian and dystopian fiction's imagined ideal or ruined society. Belongs here: a genre whose defining convention is a departure from realist possibility. Does not belong here: historical fiction, which departs from the present but not from realist possibility, tracked under the novel group above.
