Turn 10 game director Dan Greenawalt believes it'll be difficult for any other dev team to "replicate" what Turn 10 has done with Forza Motorsport 3.
"I've got huge respect for Yamauchi and what the Polyphony Digital team does, they're a great developer. But do I personally feel confident that it would be difficult for any other racing game to do this," he told CVG in regard to Forza 3's physics.

"We run our physics at 360Hz," added Greenawalt. "I don't know of any other game that does that. That takes a commitment to physics, not just about making sure you have beautiful graphics.
"Forza 2 had great physics and okay graphics. Now Forza 3 has great physics and great graphics, because we learned more about the box. But we still prioritise physics first, not graphics first. That is one of the differences.
"Gran Turismo is a great game and when it comes out I'll play it. But I think that without the partnerships and without the commitment, it will be very difficult for another team to replicate what we've done."
