I'm not referring to a "guilty pleasure". I'm talking about playing a game where your character does something you may not necessarily have chosen, but said actions made you feel really REALLY guilty afterwards? Warning, this thread may contain spoilers about games.

One game in particular comes to mind. Neir. If anyone has played the game at least through the second ending, you know EXACTLY what I mean. Here is the rundown though. During your first play of Neir, things are standard. You are on a quest to save your daughter, you kill enemies, bosses, and eventually have a happy ending. However, you are given the option to play again. When you do... you get a brand new perspective on things. Bosses you previously encountered now have tragic back stories. A small shadow creatures loosing it's mother, befriending a robot, that we eventually kill later.After that particular chapter, I felt like shit. The game really does it's best to constantly punch you in the balls for every thing you do. Even the final ending is a colossal punch to the junk.
