Development took about a year and a half, with the team aiming for as much realism as possible. Certain features, including multiplayer, were dropped. Over 15 million copies were sold, and ports for various games consoles were released, most in 1995. "Theme Park" received generally positive reviews. Reviewers praised the gameplay and humour, but criticised console ports for reasons such as lack of save or mouse support. The game received a Japanese localisation (in addition to normal Japanese releases), "Shin Theme Park", released in 1997 for the Sega Saturn and Sony PlayStation, and remakes for the Nintendo DS and iOS, released in 2007 and 2011 respectively. "Theme Hospital" is Bullfrog's thematic successor to the game, and two direct sequels followed: "Theme Park World" (known as "Sim Theme Park" in some territories) and "Theme Park Inc" (also known as "SimCoaster").
