Your self-designed character is the manager of a line of very unpopular theme parks owned by your uncle, Mortimer, who is the designer of many great theme-park-related inventions. There are five parks, with each one having three sections that all tie in to the same overall theme. For example, in Thrillville Giant, all the objects in the park are very big. Sometimes, some of the rides for the park continue the same theme. During your park's rise to fame, you have to deal with many attempts to take down its popularity, usually from Vernon Garrison, a rival character who runs another chain of amusement parks called Globo-Joy. You need to keep your customers happy so that they don't go to Globo-Joy. Throughout the game, there are mini-games and missions to be played, and there is a separate multiplayer mini-game section, as well as another section where roller coasters can be created and saved to be used in the game.
If the player completes assigned missions, thrill points are awarded. If enough thill points are gained, the player can move up to the next level.

Due to the limitations of the platform, the Nintendo DS version of the game only features seven mini-games, while other versions have over 40 mini-games.
In the Xbox version of the game, all mini-games have leader boards for Xbox Live. A demo is also available on the Xbox Live Marketplace and from the games official PC website.
This game has received mixed reception. IGN gave it a 7.5, bashing the graphics, and stating that the minigames are hit or miss. GameInformer gave it a 7, again bashing the graphics, but saying that it was also repetitive. Gamespot gave a 7.5, also complaining about the graphics, but occasionally unresponsive controls also brought down the score. The game has been rated 8.0 on Wii, and a 9.4 on Xbox by the public also.
