Sony doesn't want developers to "force" Move on games where it doesn't make sense, SCE senior researcher and EyeToy creator, Richard Marks told our man at E3.
When asked if he wanted to see every PS3 game from now on support Move, Marks said the motion controller's only one of multiple input devices supported by the platform holder.
He said: "I don't want that to happen. I love the Move but it's not the only controller on our platform. We have a great controller already - the DualShock - and some experiences are supposed to be used with that.
"A new set of experiences that use more special input - that's what's good for the Move. So I think our first-party will always continue to court both controllers."
He added: "I do not want to see somebody just force the Move on to a game that it doesn't make sense for."
In the same interview Marks gave us a great technical rundown of the Move, and explained how the colourful ball on top is "crucial" for making the controller work.
