Since none of us have played it, we can't tell you anything that you probably haven't already read on IGN, Gamespot, or other gaming news sites, or seen on the GDC conference videos of Phil Harrison's "Game 3.0" speech that's all over Youtube.
And even if we had played it, we wouldn't be able to tell you because there would undoubtably be an NDA that we'd've signed, so we haven't played it yet.
Can anyone tell me what Playstation 3 Home is like?
Well there is not really much to tell at this point, except that its an online community that is suppose to help you interact with other PS3 users to become friends and improve gaming also allows you to meet people and go online with them to play games. For all of the details check out the PS3 Home Info thread, in the link below.
