The talking of the making of Landrush, one of my favorite short track disciplines in DiRT. Looks like they're going for a very in-depth, pushing the physics and authentic vibe with the hardware, feel but also taking a play out of the Forza handbook and offering assists to allow anyone to compete. Also fictional landrush circuits are dependant on each difficulty and their are a few category of racers you can choose from - ranging from small buggies to big beefy Trophy trucks.
