Including its original incarnation on the Dreamcast as Metropolis Street Racer, Bizarre Creation has been around the block four times already with its Kudos-based arcade racing franchise. So what's going to make the fifth iteration, Project Gotham Racing 4, stand out from the rest? Inclement weather, true AI, and motorcycles. As previously revealed, PGR 4 features rain, fog, and snow. What gamers didn't know, was that they'd be racing through PGR 4's ten cities on just two wheels.
