I'm sure there will be some restrictive factor MS hasn't revealed yet. Maybe the shared versions of the game are limited like the PS+ version of Drive Club. Or maybe you'll have to pay to play online or something. I don't see how this would be a huge detriment to sales or anything though. Most people won't use it, and plenty of people who do use it, would likely end up buying their own copy when they get tired of the restrictions. Especially in a big 10 person share family.
