This was the biggest slap in the face for me. I kept playing even though I hated every minute of it, hoping it was going to start not sucking once I got to the much touted chapter 11. What a joke! I couldn't believe how short it was. I thought Pulse would at least take up a good 1/4 of the game; I had no idea the game only had 13 darn 'chapters'.
Of course technically the game does "open up" at this point, but not nearly to the degree that I expected based on what so many people had written and even what my own friends had told me (they'll never be trusted again).
