Seems like about 75% of the free kinect games, such as I Am Super, Air Band, etc... are still available for download, but they are listed as add ons, so there doesn't seem to be a way to play them... There is no reasonable answer for this, it's expected at this point.
So, what do i do? Just delete them??? Why even have them still on the marketplace if we can't play them?
Idk what to say..
