7. Shared Gaming Experiences
Sony's $300m purchase of the Gaikai cloud service means that Sony are able to enhance the shared experience of gaming ten-fold; with the PS4, you'll be able to stream your game playing experience with the touch of the Share button, allowing friends to watch you playing the game, chatting to you (either talking trash or offering support), and most amazingly of all, even being able to offer assistance and take over control of the game to get you through a difficult section. It's an alternative to a buddy sitting over your shoulder at home; now he can jump in and of play as and when you dictate, creating a more intimate, shared gaming experience that's easily one of the most impressive next-gen features we've seen so far.
