The game was created with the Chrome 4 Engine, it's not an engine that a lot of people have heard about yet, but I think in the future more and more developers will begin using it to develop games. It's a rapid game development system with advanced visual technologies, which incorporates all modern visualization techniques, advanced scripting system and impressive physics. This seems to be what really helps bring out the realism within the game as you're tearing it up around the track, gliding through the air as you hit the boost that propels you off the top of a mountain. The power of this engine is also what makes this game feel like your actually cruising on a MTX/ATV as you whip around corners. http://naildbiter.com/0rKmL
