Sony, by far, had the biggest and best booth at E3 2014. They had sections catering to all sorts of new experiences, like a section devoted to indie games, like Galak-Z, Bro Force and many others.
There was also a dedicated area for people to test out Project Morpheus, or to try their hand at Destiny, or Driveclub, or to watch the Bloodborne trailer.
Here are some photos of their booth, and the various sections and games within.
