RollerCoaster Tycoon 3
In addition to the new 3D graphics, Atari has just announced some new features available in RollerCoaster Tycoon 3. The most promising of all is the Fireworks MixMaster. With this tool you can design your own shows anywhere in the park and be synchronized with any music files you have on your computer. Also, music can be attached to any ride in the park.
There is also a brand new night cycle, which dawn, dusk, etc. so there will be a whole new element of depth in creating a night time park.
Look for RollerCoaster Tycoon 3 on American store shelves this November, only on PC.
