But the game that dominated the expo was for something no one was expecting.
The Last Guardian was first announced back at E3 in 2009 for Playstation 3, with a release date attached of 2010.
Since then, not a peep has been heard about it.
That all changed with a seven-minute gameplay demo aired during Playstation's live presentation.
Attendees heaped praise on the trailer, with many calling it "ethereal" and "beautiful" to watch.
Creative director Fumito Ueda admitted to Playstation Blog it had been so long since The Last Guardian's announcement he thought people had forgotten about the game.
"Yes, it's been a few years since our last announcement," Ueda said. "From my point of view, it was very unpredictable how the audience would react. I wasn't sure if people would remember the title. Admittedly, I was a bit nervous."
"After the announce I saw the reaction, and the cheering - and that proved to me that people had really been waiting and were excited to see (it). Afterwards, I was more relaxed and happy!"
Ueda, who created Playstation 2 classics Ico and Shadow of the Colossus, said the game's delays were due to converting it from Playstation 3's technology to Playstation 4.
"If I had to call out one of them, it was more of a technical hurdle that we had to overcome," Ueda said. "But eventually we have overcome it, and we have finally (and) proudly.
The game's mysterious storyline is being deliberately kept under wraps, he said.
"It's a story about a young boy who has been kidnapped or captured under strange circumstances. It's about an encounter between that boy and the mysterious beast Trico amidst ancient ruins, and a story about their journey together in the hope of escaping their mysterious predicament."
It currently has a release date of 2016.
