It still seems to me like people have more of a problem with this as a matter of principle than they actually will in practice. I really don't see how this is meaningfully different than the experience I already have on Steam (it works both ways Vivi ) right now, which does require me to authenticate every once in a while to access my collection. However, I do think they need to clarify exactly what happens when you don't sign in for a day, and how you remedy the situation.

The launch titles they announced this week make it seem like those 15 exclusives/IPs will indeed be a lot of Kinect and small downloadable games...
