I'm often curious about how major plot twists are pitched. Did Darth Vader revealing he's Luke's father make sense to everyone else in the room? What about when Ken Levine told his team about where BioShock was going? In the case of one of the bigger moments in The Witcher 3, the writing team was slightly flabbergasted, according to the person who came up with it.
To mark the 11-year anniversary of The Witcher 3, Pawel Sasko, a quest designer on the RPG who's now an associate game director at CD Projekt, revealed he threw out an idea for The Battle of Kaer Morhen that rendered his team speechless.
