On my first run-through of Metal Gear Solid 3, I hated encountering the Sorrow. Of course, the level wasn't hard AT ALL, but I was so foolish that I completely forgot about the revival pill. I died and went through all those ghost, not so many anymore since I keep my casualties at a minimal, about 5 times before I figured out what to do. Now, I like the level because it shows me all 9, including the fallen Cobras, of the people I killed before that level.
