BioShock creator Ken Levine has stated that the use of motion control must be "firewalled off" in order to give gamers the opportunity to opt out.

"Any experience that sits in the realm of motion play needs to be kept separate from the main experience," he said in an interview with OXM.

"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."

At this year's E3, Levine announced the upcoming BioShock Infinite would include PlayStation Move functionality, despite at one point being sceptical of the peripheral.

"Any new experience we add, we need to be able to protect this experience," he went on to explain.

"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 set to release in 2012 on PC, Xbox 360, and PS3.
