What will happen to you if Microsoft debuts a game that does just that. Remember its down the road not across the street. I am a humanitarian I hate to see suffering. Hold your pride in check with good programmers anything seems to be possible.

I wonder if this is the title in question while the name was divulged other then that its been rather secretive. Further more the scarce details match the rumor. I could conceive of a espionage game beating Metal Gear if it was a large persistent world, but I find it hard to believe that the graphics could hold up under user load. Anyway this should be a title we will see this year regardless. No platform from what I can see has been announced.
