Though he works for IOI, it is revealed that he took the job only for the opportunity to destroy the entire Oasis.
The prison identification number of the character Alex from author Anthony Burgess' novel A Clockwork Orange is also the same as Nolan Sorrento's Innovative Online Industries' employee identification number IOI-655321.Nolan is also the first name of American engineer and entrepreneur Nolan Kay Bushnell who created the video game pong and later founded Atari, Inc. in 1972 and also the Chuck E. Cheese's Pizza-Time Theaters and chain in 1977. According to "Ready Player One" author Ernest Cline, "Not that I think Nolan [Bushnell] is a bad guy, or anything. It’s meant as a subtle tribute!"
According to Cline in an interview, author Andy Weir of The Martian had emailed him and told him to come over after he had written some Ready Player One fan fiction, wherein he had written an origin story for the villain Sorrento in Ready Player One.
