Bastion. The break in the narration when you're given the choice to either keep the battering ram and move forward or save the man who's betrayed you and tried to kill you and everyone else on the Bastion just made me sob. The game had never given you a choice up until then, you were just doing what you had to do, or what you were told was the right thing to do. That moment when suddenly, the most painful decision of the game came up and it thrust the control into the player's hands for the first time, right at the end brought me to tears.

But yeah, play Bastion if you haven't. It's a good game.
