"Motion play needs to be kept separate from the main experience," says Ken Levine

Irrational's Ken Levine has said motion controls should not be enforced in games, and that the addition of the tech should be "separate from the main experience."

Speaking with OXM, Levine said experimenting with the controls is fine, but you have to protect what works and forgo what doesn't.

"Any experience that sits in the realm of motion play needs to be kept separate from the main experience," he said. "It needs to be firewalled off so that if this experiment isn't for you, or doesn't turn out to be all that great, you just ignore it.

"Any new experience we add, we need to be able to protect this experience. I like the stuff they're doing with Mass Effect 3, in terms of making some of the interface aspects a little less thorny - more the squad commands than the conversation, as that's a bit of a challenge on the controller.

"What you don't want to do is add something in and enforce it on anybody Do an experiment, fine! We're in the experimental stage, and people shouldn't be afraid of experimenting as long as we can firewall off and protect what we know works. If we don't experiment, we don't progress.

"I'm a hardcore gamer - I do most of my gaming on mouse and keyboard. I'm always open to new things, but I'm a really conservative guy at heart. I'll try it out slowly, but I'll be doing so very conservatively."

BioShock Infinite is slated for 2012, and while it will contain support for PS3's Move controller, it has not been announced whether the Xbox 360 version will make use of Kinect or not.

It will also be made available on PC.
