"The problem is when you have a lot of horsepower." So says SimBin Studio's creative director Diego Sartori, one of the driving forces behind the studio's upcoming racing debut on the Xbox 360, RacePro. Long known for its heralded PC sim-racing games, including GTR, GTR 2, and last year's Race 07, the studio is branching out with RacePro, a game that the studio hopes will please hardcore racing fans and perhaps create a few new racing fans along the way. Gamespot had the chance to spend some time with an updated build of RacePro and, yesterday, they spoke with Sartori about the game's evolution on the Xbox 360.
