During Sony’s E3 2015 presentation, Media Molecule announced their next game, Dreams for the Playstation 4.
You explore the dreams of others and than allow people to enter your dreams. They created a new creation tool to allow users to create their own worlds. It uses a mix of motion controls and button presses on the Dualshock 4 to make your worlds. It currently appears to be an interative world to explore, more than a game.
