Star Trek director J.J. Abrams and Valve president Gabe Newell showed up at the 2013 D.I.C.E. Summit where they delivered a keynote speech on Storytelling Across Platforms: Who Benefits Most, The Audience or the Player? Last week a little clip of the discussion was released online, but today we bring you the full 20-minute discussion, and it's definitely worth watching! It's fun watching the two banter back and forth about different storytelling elements. The two are currently working together on developing big screen adaptations of Portal and Half-Life.
