Although not a classic, but good

With part 3 came in 2004 for the first time 3D technology is used, so you can experience the roller coaster ride from the visitor's perspective. In short, the game had given me a lot of fun, but mostly through add-ons of fans. This game lives mainly through the genius of amusement park fans who provides the game a variety of roller coasters, theme, rides and stalls. This one almost no limits.
Clear, on part 1 + 2 it is not 100% off, but you can invest in the park a lot of love and time, so that at the end of a really convincing, well-made amusement park may arise.

The add-ons "Soaked" and "Wild!" are also well done and offer themes to water, swimming pool, as well as zoos and animals and some many new attractions, tasks and subjects, or scenes.

Strong buy recommendation for all Theme Park and simulation fans.
There currently is "RollerCoaster Tycoon World" (again, Atari is the publisher) developed to the end of 2015 should appear.
