We won't know now because it's not there anymore. But did you actually believe they would let you share a full game ? I believe more in it having been a timed play followed by maybe some annoying prompt to check the rest out from the market. Had they been more honest about the real way it worked we could have known. But I have a feeling there was something like this in there that they didn't want to publicly state.
Given that sharing the full game simply means only one person playing at a time, yes I believe it is possible. For single player games it would be no different than it is now. You finish playing and then hand your disk off to someone else and they play. For muliplayer games, sharing would have been far less effective. One person playing at a time does not allow groups to play together. This would have let you "lend" the game to a friend to convince them to play, but they still would have had to buy their own copy to play WITH you.
I've seen some people with the belief that 10 people would be able to share the same game simultaneously. I never took that away from anything I read. That would be insanity.
It doesn't pass the logic test that a corporation bent on huge DRM and who equates used games as piracy would allow unhindered sharing of titles with 10 people at a time. This would decimate sales far more than used games ever would, in particular single-player games without a lot of replay value could be passed around easily.
If one buys that at face value without examining the overall agenda at work (this goes for Sony as well of course), then I can't really help you.
Sometimes it's correct to by cynical, and just on a dollars and cents outlook, sharing games with 10 people with different XBL accounts without some sort of hourly limitation would never have flown with publishers. They'd even have hard data in real time to show them how much money they think they're losing. "Look, people have logged 750k hours this week in family shared titles, and that has only led to XX purchases of those titles for the people in the sharing plan, this is losing $ for us".
Too good to be true = too good to be true. Every single time.
Look, it's obvious from your posts that you have your mind made up and nothing I or anyone says is going to change that. Still, your belief does not equate to fact either. The message from every REAL Microsoft employee has been the same. I'm willing to give them the benefit of the doubt until proven otherwise. Unfortunately, for the time being, we won't get the chance to find out.
I can't tell from from your posts if you are one of the people who seem to believe that they were going to allow 10 simultaneous users to play together. If this is what you understood, then I agree it would be insanity. However, none of the official statements I read ever suggested that. One at a time is the way I understood it to work.
You are welcome to be as cynical as you want. You are welcome to have any opinion you want. Passing those opinions off as fact, backed by some anonymous blog purporting to be an MS employee doesn't fly.
