After finishing Human Revolution and watching all the endings, I noticed that in each one the narrator mentioned "trying to follow morals" or something similar, which sounded to me like a reflection of my playing style.
I've since read elsewhere that the ending narrations do indeed change based on what happened during the game, although I have found no mention of (a) what causes the changes, and (b) what the different possible narrations are.
So...
- What can cause you to receive different narrations over the endings?
- What are the different narrations, or where can I find a transcript?
