In 2001, Disney began to consider producing a sequel, but rather than using stop motion, Disney wanted to use computer animation. Burton convinced Disney to drop the idea. "I was always very protective of Nightmare not to do sequels or things of that kind," Burton explained. "You know, 'Jack visits Thanksgiving world' or other kinds of things just because I felt the movie had a purity to it and the people that like it... Because it's a mass-market kind of thing, it was important to kind of keep that purity of it." The 2004 video game The Nightmare Before Christmas: Oogie's Revenge did continue the story of the film, with Capcom's crew of developers going after Burton for advice, and having the collaboration of the film's art director, Deane Taylor. In 2009, Selick said he would do a film sequel if he and Burton could create a good story for it.
Characters from The Nightmare Before Christmas have also had cameos in Disney and Square Enix's role-playing game series, Kingdom Hearts. In the majority of these games, Jack acts as a partner to the main character. In the first game, Jack attempts to liven up Halloween by giving a heart created by Dr. Finklestein to a Heartless, but the experiment goes wrong and the heart soon is taken by Oogie Boogie. In Kingdom Hearts: Chain of Memories, he tries to help the protagonist, Sora, regain his memories. In Kingdom Hearts II, Halloween Town and its inhabitants are seen, while Jack rekindles his notion of taking over Santa's job. In the prequel game Kingdom Hearts 358/2 Days, Jack seeks inspiration for livening up his Halloween by paying attention to the actions of the protagonist, Roxas.
