After the announcement of the 1993 Jurassic Park feature film, based on the critically acclaimed novel by Michael Crichton, developers Ocean Software, BlueSky Software and Sega were licensed to produce games to be sold to coincide with the release of the film on the popular platforms of the time. In 1997, several developers, including DreamWorks Interactive and Appaloosa Interactive, produced various games for nine different platforms to coincide with the release of the film, The Lost World: Jurassic Park. For the 2001 film, Jurassic Park III, a total of seven games were produced, including three games for the Game Boy Advance and three PC games. Lego Jurassic World, released in 2015, is based on each of the series' four films, including Jurassic World. Since 1994, a number of other video games that are not based directly on any of the films have also been released.
