Horizon Forbidden West: Burning Shores players were quick to notice that Aloy is much less talkative during the DLC's puzzle sections, and they were equally quick to celebrate because constant puzzle spoilers were really annoying in the main game.
This is partly a consequence of there being fewer puzzles in Burning Shores, although this change isn't called out in the DLC patch notes. But it does appear that, like fellow PlayStation Studios hit God of War: Ragnarok before it, Horizon Forbidden West has deliberately given players more time to, you know, solve puzzles on their own.
