" @Zenaxzd: I loaded up my save when I hit chapter 11. It reads 27 hours (few minutes to 28), so I was off by three hours. There are choke-points in the game where you can grind for experience, so perhaps that might be an answer for you. "I didn't do any experience grinding prior to Chapter 11 and made it there in between 20-25 hours. I had played it for about 60 by the time I was done with the main playthrough and have yet to tackle all of the optional content.
