  • Our ongoing goal for Flight Sim World is to look for ways in which we can advance flight simulation beyond the types of experiences available today. Simul’s trueSKY offered the kind of leap in weather and sky technology we needed in order to make this happen.

    Stephen Hood, Executive Producer, Dovetail Games

  • Motocross is feeling your bike in off road and wild contexts. Achieving this result in a video game is really challenging because you want the environment to look alive. TrueSky allowed us to ride across our compound areas with seamless variations between sun, rain and clouds, bringing a whole new level of realism in our motocross experience.
