Gaming is often a social venture, especially in the age of online games, and 'My PlayStation' is a new platform that brings the social aspect of gaming outside of the game consoles themselves. The new service extends the PlayStation Network, Sony's social gaming system, onto browsers and mobile devices, making it easier for gamers to socialize and organize even when they aren't at their consoles.
My PlayStation is available through the most popular browsers on both Windows and MacOS, and it can also be accessed through the PlayStation app on iOS and Android devices. The My PlayStation profiles are much the same as on the PlayStation Network, displaying gamers' various trophies as well as the online statuses of the other gamers they're connected with.
