Sony has spoken of its "surprise" over Microsoft's casual launch line-up for Kinect.
Microsoft unveiled Kinect at E3 last month with a wealth of Wii-esque titles, including Kinectimals, Kinect Sports and Joyride.
Sony worldwide studios boss Shuhei Yoshida told the August issue of Edge magazine that he respected Microsoft's strength with FPS games.
However, he said he was bemused by its family-friendly approach with its new motion sensing peripheral.
"In practical purposes, those are Microsoft's strengths - they have very strong FPSes, for example," he said, "and they work with Activision to provide content for Call Of Duty.
"It's very interesting to see them confirm where they have those strengths by opening [their E3 presentation] with those games.
"When they showed Kinect I was surprised to see so much on the casual side. It was a polarised kind of approach."
Yoshida said that Sony's approach was more widespread. "We are not focusing on one area, or two areas, but covering a full audience spectrum," he added.
