I have no words for this act. At least nothing that seems coherent. Finished my first play through about ten minutes ago. Just kind of leaned back and went "well, f---." Very few games have ever taken me on such a roller coaster of emotions. I can't really go into details without peppering this with spoilers, but dear lord my heart's in a million pieces.
To anyone reading this, do yourself a favor and get this game. You'll laugh, you'll cry, you might yell at the screen (i did, repeatedly), and you'll probably feel like a terrible human being at least once. It really put me through the whole gambit of human emotion and any story that can do that is one worth experiencing.
