Hmm, about home. It's an interesting concept for a console but it all comes down to implementation. As an answer to the gamerscore system of XBox-Live, it fails. Menus and charts just work BETTER than some VR trophy room. As a community building tool, it has the potential to do things that Live can't.
I DO hope they open up the scripting system for the arcade games so that users can create their own, but I don't see it happening.
