PS4 users will have the ability to create communities based around shared interests, like games, genres, and more. Communities include a message board with general discussion, screenshots shared by players, and the ability to join parties / games.
From the PS4 system’s Messages app, you’ll see a new option for Stickers. The 3.00 update will contain stickers themed around Uncharted 4: A Thief’s End, Knack, LittleBigPlanet 3, Resogun, and more. Instead of typing out a message, just send a sticker — like Drake looking at a watch, asking you to wait a minute.”
