Good Good. It’s a step in the right direction. Gaming is “another Internet” : many people you may never see on Facebook or on a forum somewhere, whose name you’ll never see, are currently trapped, only able to see those on the same platform as they.
But this will open up their worlds, and for games that are already on each of the systems (PC, XBox and Playstation), this move is very logical.
The other major system, the Wii U, will remain in its own zone but Nintendo has always had their own realm, all the way back to the 1980s.
