Xbox boss Phil Spencer has said the studio isn't "forcing" Kinect on Sports Rivals developer Rare which he said is "evaluating" what to do next following the game's launch and Microsoft's decision to un-bundle the sensor from the Xbox One.
Spencer told Official Xbox Magazine:
“[Rare has] just come off the successful launch of Kinect Sports Rivals. I think I’ve heard a few times from people asking about Rare – they’re in the process of evaluating what they want to do next, and we’re working closely with them to see what their new project will be.
“And I’ve also laughed when people have tried to use the word, what I 'force' them to do – if you’re around any independent studio, or like Rare a studio that’s independent-minded, you’ll know that forcing a studio to do something is never a successful equation. So they’re free to look at all different kinds of opportunities, they always have been, and we’re having a great time trying to work out with them what their next game might be, but we have nothing to announce right now.”
Based on his remarks, the UK studio isn't required to use Kinect in its games even though all of its most recent output has involved the sensor.
