Atari announced that RollerCoaster Tycoon 3 has shipped to the US retail stores and carries a suggested price of $39.99 - the game will be available in Europe three days later. The latest installment in the Rollercoaster Tycoon series developed by Chris Sawyer and Frontier Developments includes innovative new photo features and a full version of Microsoft Photo Story, which will enable players to tell the story of their park experience and share it with their friends. New scenery items called Photo Spots can be placed in a park and enable park guests, "Peeps," to pose for the camera. In addition, cameras can be placed directly on roller coasters to take shots of guests as they ride. The game also features new gameplay elements that fans have been asking for, including diversity of guests, group behavior and improved guest AI, assigning music to rides in the park, day and night cycles with weather effects, a park lighting system and more. Also, the Fireworks MixMaster feature allows you to design fireworks displays and choreograph them to the music of your choice - you can use pre-set in-game songs or your own MP3 files. Be sure to check out the demo if you haven't done so yet.
