Again, as I said with the same feature for the One, it's awesome, but I just don't see the point when you're going to have to download at least half the huge file before doing so. If it's a 20GB file, you're still going to have to download 10GB+ of it before you're able to start playing it. It's a cool feature, but I'll never use it.

Now if the One or PS4 want to implement what the Xbox One WAS going to do and allow sharing of games, I'm all in for that.
