Finally finished this game, including the DLC (which was quite short).
On reflection, this is probably the best story told in a game. The execution of story and the likability of the two protagonists, as well as their character development throughout the game was the pinnacle of a masterpiece. The game play itself was very good, and I enjoyed the juxtaposition of calmness to chaos.
However, I found the perfectionist in me kept wanting to replay encounters to reserve the scarce resources. Although, the game became more enjoyable once I stopped caring about any of that and just shotgunned or bow an arrow'd anything in my way, with tact of course.
Overall, brilliant.
