Theme Park Inc
Theme Park Inc (also known as SimCoaster) is the last game of the series that started with Theme Park in 1994 and continued with Theme Park World in 1999. After that, Electronic Arts has made no more games based on building amusement parks.
Theme Park Inc (as stated on their official website -- currently taken down but previously accessible through the Theme Park World portal) attempts to focus more on the management part of the park than on the actual rides. This, however, is contradicted in the SimCoaster Official Website (still online as of September 2006) which highlights the new Roller Coaster editor.
The main innovation Theme Park Inc introduced over Theme Park World was the simultaneous handling of several parks, each built to a different theme, shown on a globe reminiscent of Theme Park World. Since the themes were preset since the beginning, their diversity was limited in comparison to those available in Theme Park World; however each theme offered many new rides to be built, in addition to the Roller Coaster editor mentioned above. A unique feature was a first-person mode - allowing one to play as a park guest and ride on attractions.
