Sim Theme Park

Theme Park World tasks players with managing a series of amusement parks. To do this, the player must choose how to spend their funds, finding ways to expand the number and scope of their parks while remaining profitable. Money can be used to purchase things such as new rides or attractions, and hire staff to maintain the park. As in its predecessor Theme Park, the staff available for recruitment include mechanics, cleaners (known in some versions as handymen), entertainers, and guards, but Theme Park World also introduces a new role: scientists (known in some versions as researchers).

The staff repair rides, clean litter, entertain visitors, ensure the park's security and research new rides, shops, and attractions. Staff can be trained to make them more efficient, and require frequent rest in staff rooms.

Theme Park World was announced (as Theme Park 2) in April 1999. Many Bullfrog personnel had wanted to produce an updated version of Theme Park. Producer Jeff Gamon said that and that players wanted to ride rides they created and Bullfrog built on the original game's success using the latest technology. Gamon also said that Theme Park World would be less objective-based and more open-ended than the previous Theme games. Early in development, there were 12 artists, who were led by Darran Thomas before he left Bullfrog with Jeremy Longley and Glenn Corpes to found Lost Toys.

The game used a 3D engine to eliminate the need for a 3D accelerator card, and an advanced behavioural artificial intelligence system (programmed by Ben Board) that gave visitors different behavioural traits. Board said that the most important feature was the queuing behaviour, and that he spent a while making it look interesting when visitors were in long queues. Many management features of the original game were retained, but some, such as supply ordering and competition with other parks, were removed. Staff would no longer get strike action because it was considered confusing and annoying.

Theme Park World received generally positive reviews, though it failed to match the success of its predecessor. In North America, it sold 309,516 units and earned $8.51 million from January through October 2000, according to PC Data. These figures rose to 563,299 units and $13.08 million by the end of 2000, which made Sim Theme Park the region's eighth-best-selling computer game for the year. In 2001, the game took ninth in the United States for the year, with sales of 514,288 units ($9.92 million). The game was later given a "Platinum" sales award by the Entertainment and Leisure Software Publishers Association (ELSPA), indicating sales of at least 300,000 copies in the United Kingdom.

The PC version was praised highly by Robert Coffey of Computer Gaming World: he believed the game is "Wildly entertaining" and liked the ability to tour parks and ride rides. His only real criticism was the difficulty of constructing roller coasters. The game was awarded the Editors' Choice award. A reviewer from IGN described the presentation as "clear, concise, and fun", and was impressed with the sound.
