VideoGamer.com: You mentioned early that you're not afraid of championing the PlayStation 3, and that the platform is your lead format. Why is that?
NC: At Criterion we've always lead our development on the Sony platforms. We feel very at home on them, we a big fan, we think the Sony machines have always been great. We love PS3. We really like 360 as well but we made a conscious decision to lead on PS3 and that's given us a great 360 title as well. We've always led on the Sony platforms and we didn't feel that this generation should be any different, and I think we've reaped the benefits from doing that.
