We knew Cyberpunk 2077 dialogues would be pretty hardcore. Fans of Polish developer CD PROJEKT RED are well aware of their penchant for long conversations between the player character and the various NPCs that populate the game world.

However, it looks like Cyberpunk 2077 might go on to set a new standard. In a recent interview with INNPoland, CD PROJEKT RED Story Director Marcin Blacha said that Cyberpunk 2077 dialogues take up 'two thick books' worth of writing. That's not considering all the other text and documentation created for the game.
