My favorite (and quickly becoming the only sort I can tolerate) of npc dialog is where it shows the scene of them speaking with the voice over, but also shows the subtitles and you can skip to the end of the sentence without skipping the whole thing. Now when I play a game with skippable cutscenes that don't do that I have to physically hold myself back from trying to skip it, and if it's unskippable altogether I just get ptsd.
