The Witcher 3 has a number of timed conversation choices for you to make. If you take too long then fate will decide for you.
Often, a bloodbath can be averted (or created), at the last moment.
Also: some of these timed choices are also fundamental to how the story turns out. Do you want the “good” ending or the “bad” ending?
On a related note, I do find myself playing the game the same way, during each playthrough. I prefer the “good” endings, if possible, and find it quite difficult to be a “bad” Geralt.
