It makes you look at humanity in a different way with each play through, not just the harsh and unforgiving humanity that exists in the zombie apocalypse, but the harsh and unforgiving humanity that exists around us in the world we live in now.
No going back is the right ending for the second season of The Walking Dead, and it succeeds in delivering a Clementine that's really the player's character.
When describing the 3rd episode of the season, In Harm’s Way, I compared Telltale to a maniac who lives to torture his victims. No Going Back only reinforces this impression.
