For me, it’s cutscenes in general. I know there are people who do care in general, but for me a game where I care about the plot is very rare. And the examples I can think of (Outer Wilds, or Ico, for two examples) either have no cutscenes or very few brief ones, and tell the story in a different, more immersive way.

For me, a general rule is - if the game forces moments on me when I can put the controller down and wander into a different room, then that’s not what I’m interested in. I want to actually play the game.
