The So Many Me game has an add-on already for $2.99, I also noticed this while reading the description from the Xbox One: "Active Xbox Live Gold membership to play downloaded Xbox One games. Kinect required for some games."
So we may see Kinect only games as GwG soon?
I think that's been on there since GwG started. But so far no Kinect games have been part of the program. If they ever did give a Kinect game I'm sure everyone would start crying about how awful Microsoft is.
