Secrecy. The video mentions how a dev got fired because they answered a community question after the trailer was released, about a feature that was already in the game. They also hired people without telling them what game they'd be working on, and only got juniors who didn't play the original. Then when the studio imploded and the publisher offered to transfer hire the old engineers, only 4 people accepted. Because they didn't actually care about the project. It strikes me that the game industry gets away with so much because the developers are heavily emotionally invested in their own project, and the publishers are so used to this, they take it for granted. In this case, that wasn't actually true.
