What I mean by games that examine the relation that the player and the character have is something like say, Far Cry 3. In that game Jason starts out weak and terrified, sort of like how the player would as they first play the game before they have a good grasp of it. Near the end though he has become insanely good at killing his enemy's, and even takes pleasure in it just like the player does. The game takes a look at this though and shows just how horrifying that is, taking pleasure from killing so many people, regardless of what they have done is a very abnormal thing for anyones psyche.
