Check it out. I asked YOUR questions in this interview with Project Gotham Racing 3 dude Chris Novak.
"Likening PGR 2 to PGR 3 is like comparing Polaroid to Imax. Bizarre’s graphics devs have posted a number of goodies on their website, and what’s ironic is that their "in development" in-game shots are currently the subject of much debate on a few game sites: ‘That can’t be in-game.’ It is."
P.S. If you sent in a question, I asked it. If you don’t see it here it’s because either Chris wasn’t allowed to answer it at this point, or I wasn’t allowed to publish the answer. Now I just gotta get me a ride in the Viper…
