Eurogamer: How did PS Move integration come about?
Mathieu Girard: [...]
We had this first prototype. We showed it to Sony. Some of the guys in London were very enthusiastic about it. They have us some feedback on how to improve it.
We went back to work. We polished everything. We added lots of immersive controls, like opening the menu, like being able to navigate inside the menu with the Move, not with some kind of directional stick. Now we have something that is final.
I would say that the Move integration was very quick [...]

Eurogamer: When did you first begin working with Move on R.U.S.E.?
Mathieu Girard: I would say four or five weeks ago.
Eurogamer: Only four or five weeks ago?
Mathieu Girard: Yes.

Eurogamer: So there's no impact on the performance when you use Move?
Mathieu Girard: We've been fighting for performance on console since the beginning of the project. The last thing we wanted was to have to find another 30 megabytes of memory somewhere, or some more optimisations to do because of the Move. This was not the case.

This bodes really well for Move, hopefully more developers will see just how easy doing a good Move implementation can be and have a go at it.
