Planescape definitely belongs in the discussion. It's really the opposite of the games I mentioned though: It's crushingly dialog-heavy. Sometimes the dialog options that it gives the player are paragraphs long, so that if you want to make sure you pick the proper choice you have to stop for ages at each branch and read through them all. Personally, I don't consider that to be especially good storytelling.
