No Limits is a serious roller coaster simulator, based around (but less complex than) programs that actual designers use to create rides. Therefore, it can be very boring or frustrating for those looking for something they can pick up and master in a few hours. However, if you can understand the CAD application which allows you to create your coasters, you will find one of the most amazing and realistic simulators availible today. The software allows you to recreate any existing rollercoaster with perfection, and ride it in any seat or train of your choice. If you fancy being a ride-op, then you can dispatch your trains, activate emergency stop, open gates, raise and lower restraints, etc. - it is all there.

Finally, there are a huge number of tracks available for download so there initial low price is incredible value considering the wonderful virtual coasters you can download and ride, as well as create.
