Yesterday, Quantic Dream Founder and Heavy Rain developer David Cage debuted the 'Kara' short film . No, it wasn't a trailer for a new game but rather a trailer for the engine the development house is using on its next project. If you haven't watched the video, it's stunning -- using mo-cap, vocal and facial performances that were all captured at the same time. We grabbed Cage after screening the trailer, and got him to spill on a number of hot topics.

"We just wanted to take more risks, have new challenges and try new things," Cage said. "What you need to know about Kara is that this demo is a year old. So this is where we were last year regarding the engine and everything.""We had thought we had done a pretty decent job on Heavy Rain, and we just realized we didn't do anything with the hardware. We could do much more than that, and this is what we intend to do in the near future," Cage said. "There's still a lot to do with the PlayStation 3 I'm telling you.""We are exclusive to Sony right now," Cage said. "We're open to all options [such as becoming a first-party studio], but again, we're not a studio driven by money. It's an important element, of course, but it's not like 'Tell me how much money you give me and I'm going to do whatever you want.' ""It's always better to shoot when you know why you shoot," Cage said. "Finding the balance is still something we need to achieve in this industry. We think it's of paramount importance, other people don't give a sh*t, and that's fine.""This is not something really popular to say, but I think there's something wrong with used games," Cage said. "People make money out of our work and this money doesn't go back to us creating the content or people taking risks -- financial risks -- to make this happen."
