I used one just the other day in L.A. Noire, it had been a while since I played and I needed to remind myself what the case was about.
Also I used these quite a bit in a game called Chronicles of Mystery: The Tree of Life... but that was mainly because the dialogues went on forever and I found it more enjoyable to click through them and then read the transcript. But I would have preferred better/shorter dialogue in the first place....
