"Downpour" I think would be a more likely term.  :)

I  believe this is the problem with most people thinking.  We are not talking about synchronous 3d Graphics we are talking about physics.  We are talking about calculations not sending over any graphical over the wire.  People need to understand first what is actually being said before making statements or saying something can or cannot be done.  Its very evident that its being done what we do not know is the implementation.

So if my internet connection goes down then it'll be less impressive?

What if my internet connection isn't fast enough to ensure "full cloud compute" for this game? Are they going to make it scalable?

Just two questions that I believe make this whole thing very impractical and not worth it.

I don't buy it - sorry.

Lets think of this in another way.  If you are playing a MMO or a game that requires you connected to the internet like Titanfall, The Division, Destiney Playstation Now and a few more games I cannot remember that are coming out.  If you internet fail what happens when playing any of those games.

So if Crackdown is a game that requires an internet connection what is the difference??

If your internet is not fast enough just like any game that depends on the internet I am sure they would list that as a requirement for the game.  People are really trying hard to think of scenerios where cloud compute has any issues outside of what we already see for games today that require internet.  On the client end which is your PC or console, there is nothing new that cloud compute will introduce then any other scenerio that rely on an internet connection.

The problem here is that you aren't think hard enough about what I am saying.

Cloud compute differs substantially from streaming a full game and online play. SUBSTANTIALLY.

Millions of people who plays MMO or multiplayer games still experience lag and latency currently. What makes you think that wouldnt happend with cloud computing. We are talking about up to a million people logging on and playing a game that uses cloud computing. This is not the same thing as streaming movies through Netflix or streaming games through Playstation Now.
When you talk about real life scenarios and real life use of cloud computing, you have to think about the worst case scenario. This worst case scenario is that it can be possible that every single XB1 owner can potentially log on the server all at the same time and use the cloud computing. Microsoft claim to have 300,000 servers (possibly more) this is not even close to enough servers. Remember Microsoft is a software company, not only they will be using this for XB1 but they will be using their servers for other application as well.

If it was from Sony was believable 

So the game is gonna be online only?  Interest lost...

This have been addressed by Microsoft so many time. Cloud on the Xbox One will be use to compute task does not require to be sync. there will be lag between the Xbox and the Servers but it will not result in an actual lag in the game.

Yes but the differences is all win. Cloud compute require lesser bandwith, it isn't dependant on lag or latency issue. Microsoft already stated that with a connection of 1.5 Mbps you would be fine. The world-wide average bandwith is about 2.9Mbps.http://www.examiner.com/article/xbox-one-has-a-1-5mbps-download-speed-internet-requirement

  So what's the big deal?
