According to Microsoft Game Studios head Phil Spencer, Kinect will most likely be supported in all future first party games for the the 360.
"It's not a mandate that everything we do in first-party has to support Kinect right now," he said. "But I will say, specifically with voice, that there are some things that just seem to make navigating and playing games so much easier, that I would guess the answer will be yes in the end, that you'll see all first-party games using some form of Kinect functionality."
So what do you think? Is Kinect a good fit for EVERY kind of game?
