So these franchises will be built over a long term. What we've seen today is the starting point, but all of those games — Bayonetta, MADWORLD, Infinite Line — won't be one-offs. They're all uniquely different enough from everything in their space to build complete franchises out of. The whole foundation of Platinum Games is built around that long-term strategy.

They've been in the business long enough to know what works, and they really want to pretty much establish themselves as gaming gods.
