In a presentation given during GDC 2019, God of War director Cory Barlog revealed the full story behind the famous E3 2016 demo that debuted the new God of War to the world.
Barlog says the team always knew the game’s big reveal would be at E3 2016, though he didn’t know if it would simply be a logo, a trailer or a full demo. Nine or 10 months before the show, he decided the demo would take place inside the game’s mountain, and pitched this idea to Sony and PR representatives
“About halfway through the pitch I realized ‘this is absolute crap.’ But I’m still giving the pitch,” said Barlog. “So in my mind, I’m starting to think of ways to eject. I start having a few ideas – potentially the beginning of the game, a few visual ideas that are coming up while I’m just running on autopilot on the pitch.”
