Home is not an original Sony concept in the first place. First off its most likely a second life clone. Not that the concept originated there necessarily. Hell I remember a similar concept on the Game Cube this sickeningly cut game called Animal Crossing. The whole plot of that game was socializing with cute critters, and decorating a house. I will also say this Home seems to clone many of the engines in other Sony games. So yeah really original.
Microsoft has tried repeatedly to get Second Life on to their console. They have talked about it often enough. Further more they have spent money on virtual world development in the past. Even though those attempts were eventually abandoned or sold off. So to assume that Microsoft is doing something similar to Home, because of what Sony is doing is asinine. They are doing it, because they have been doing it all along in the first place.
The genre of shoot the shit worlds is popular right now. Here is hoping that Microsoft adds some combat or competition to their virtual world. Perhaps let us run over each other with lawnmowers. You know keep that edge.
