Game Room is designed to add more 'Classic' games to the XBLA, something people have been clamoring for. At the same time, a lot of people would not be willing to even try out something like say Adventure if it was a direct port, and not only that, but it would be damn hard to make achievements for such a game.
I do not really get it. People complain that the platform is focusing too much on multimedia and then they go out and make something that will eventually play "Over 1000" older games and people complain some more.
If you want to hang out with your friends, play games and decorate your own house go play Animal Crossing or something, even then you would not be really 'Hanging out' with your friends as it is just a digital representation of themselves to begin with, chatting over mics is seemingly more engaging. I can see why you would want them to add these kind of features, but I do not see how it would be an overall selling point for you, considering what they want and have set up with the platform.
