Halliday had many well-known obsessions. Chief among them were classic videogames, sci-fi and fantasy novels, and movies of all genres. He also had an extreme fixation on the 1980s, the decade during which he’d been a teenager. Halliday seemed to expect everyone around him to share his obsessions, and he often lashed out at those who didn’t. He was known to fire longtime employees for not recognizing an obscure line of movie dialogue he quoted, or if he discovered they weren’t familiar with one of his favorite cartoons, comic books, or videogames. (Ogden Morrow would always hire the employee back, usually without Halliday ever noticing.)
