Couldn't agree more. I remember dialog being more involved and engaging when I was reading it. I think the main reason for this is that when everything is fully VO-ed you simply can't afford to have long, lengthy, engaging dialog (a la Planescape) without paying an arm and a leg AND/OR running into really bad voice acting. When it's mostly written, well.. the sky is the limit, and it really keeps the game much more creatively fresh.
