The problem with skipping scenes is, well, you never know what you are going to miss. When I was faced with the sappy Snow/Serah scenes in FFXIII I wanted to skip them, but what if something significant happens at the end and I miss it. You can't always tell what you will be missing if you skip something. The worst thing is to skip a scene that is boring and has nothing happening, only to find yourself dropped into a completely unexplained circumstance.
